Calvin’s view on church discipline and unity: a South African perspective

Directory of Open Access Journals (Sweden)

P.J. Strauss

2010-07-01

Full Text Available The reformer John Calvin, born in 1509, considers discipline and unity as two essential aspects of the Christian church. According to him, the bond of church discipline is a way to unite church members in the truth of the Word and the Christian faith based thereupon. If discipline is exercised with exaggerated strictness and without compassion, tolerance and love, it can break the unity. Because church unity is essentially a unity of faith, or a unity in the truth of the Word, discipline can sever adulterated elements that threaten the unity from the church. Discipline, if correctly ap- plied, builds the unity of the church as a unity in religious truths.

The Unity connecting module, part of the International Space Station, is placed in a work station in the Space Station Processing Facility (SSPF). As the primary payload on mission STS-88, scheduled to launch Dec. 3, 1998, Unity will be mated to the Russian-built Zarya control module which should already be in orbit at that time. In the SSPF, Unity is undergoing testing such as the Pad Demonstration Test to verify the compatibility of the module with the Space Shuttle, as well as the ability of the astronauts to send and receive commands to Unity from the flight deck of the orbiter, and the common berthing mechanism to which other space station elements will dock. Unity is expected to be ready for installation into the Shuttle's payload canister on Oct. 25, and transported to Launch Pad 39-A on Oct. 27.

Construction of Scaling Partitions of Unity

Directory of Open Access Journals (Sweden)

Ole Christensen

2017-11-01

Full Text Available Partitions of unity in ℝd formed by (matrix scales of a fixed function appear in many parts of harmonic analysis, e.g., wavelet analysis and the analysis of Triebel-Lizorkin spaces. We give a simple characterization of the functions and matrices yielding such a partition of unity. For expanding matrices, the characterization leads to easy ways of constructing appropriate functions with attractive properties like high regularity and small support. We also discuss a class of integral transforms that map functions having the partition of unity property to functions with the same property. The one-dimensional version of the transform allows a direct definition of a class of nonuniform splines with properties that are parallel to those of the classical B-splines. The results are illustrated with the construction of dual pairs of wavelet frames.

Metric Structures on Fibered Manifolds Through Partitions of Unity

Directory of Open Access Journals (Sweden)

Hulya Kadioglu

2016-05-01

Full Text Available The notion of partitions of unity is extremely useful as it allows one to extend local constructions on Euclidean patches to global ones. It is widely used in many fields in mathematics. Therefore, prolongation of this useful tool to another manifold may help constructing many geometric structures. In this paper, we construct a partition of unity on a fiber bundle by using a given partition of unity on the base manifold. On the other hand we show that the converse is also possible if it is a vector bundle. As an application, we define a Riemannian metric on the fiber bundle by using induced partition of unity on the fiber bundle.

Disease prevalence and the index of detectability: a survey of studies of lung cancer detection by chest radiography

Science.gov (United States)

Kundel, Harold L.

2000-04-01

A survey of 12 studies of lung cancer detection with cancer prevalence ranging from 0.9 to 476 cancers per 1000 showed that the unit-slope index of detectability, d', decreased from a high value of 3.9 at low prevalence to 1.4 at high prevalence. A proposed explanation is that the readers are operating on an ROC curve with a slope that is less than unity approximating 0.6. On such a curve, a shift to more stringent criteria that occurs with decreasing prevalence in order to minimize false positives, would result in a increased unity- slope d'.

Inseparability of science history and discovery

Directory of Open Access Journals (Sweden)

J. M. Herndon

2010-04-01

Full Text Available Science is very much a logical progression through time. Progressing along a logical path of discovery is rather like following a path through the wilderness. Occasionally the path splits, presenting a choice; the correct logical interpretation leads to further progress, the wrong choice leads to confusion. By considering deeply the relevant science history, one might begin to recognize past faltering in the logical progression of observations and ideas and, perhaps then, to discover new, more precise understanding. The following specific examples of science faltering are described from a historical perspective: (1 Composition of the Earth's inner core; (2 Giant planet internal energy production; (3 Physical impossibility of Earth-core convection and Earth-mantle convection, and; (4 Thermonuclear ignition of stars. For each example, a revised logical progression is described, leading, respectively, to: (1 Understanding the endo-Earth's composition; (2 The concept of nuclear georeactor origin of geo- and planetary magnetic fields; (3 The invalidation and replacement of plate tectonics; and, (4 Understanding the basis for the observed distribution of luminous stars in galaxies. These revised logical progressions clearly show the inseparability of science history and discovery. A different and more fundamental approach to making scientific discoveries than the frequently discussed variants of the scientific method is this: An individual ponders and through tedious efforts arranges seemingly unrelated observations into a logical sequence in the mind so that causal relationships become evident and new understanding emerges, showing the path for new observations, for new experiments, for new theoretical considerations, and for new discoveries. Science history is rich in "seemingly unrelated observations" just waiting to be logically and causally related to reveal new discoveries.

Unity behind diversity in Nature

International Nuclear Information System (INIS)

Pati, J.C.

1980-01-01

The unity of the basic forces of Nature and the unity of all basic matter form the main theme of this paper. Recent developments in the theory of fundamental particles are reviewed. The 'quark' concept is described. Conclusion is drawn that the proton, neutron, hyperon and the sigma particles belong to one Baryon family. The Lepton family of electrons, muons and pions is also described. The quantum numbers isospin, strangeness etc. are explained. The nature of the four different basic forces viz., gravity, weak, electromagnetic and strong forces are discussed. Arguments are presented to indicate that the differences in these forces are described at low energies and that at high energies of the order of 10 5 BeV the three forces electromagnetic, weak and strong, merge into one and the same force and at the same energies quarks and leptons interact universally exhibiting their oneness. The stability of the proton is discussed. Future trends are indicated. A fundamental substructure 'preon' is proposed. (A.K.)

Gnosticism, church unity and the Nicene Creed

Directory of Open Access Journals (Sweden)

C. F.C. Coetzee

2008-07-01

Full Text Available Gnosticism (derived from the Greek word “gnosis; knowledge” is the well-known phenomenon or movement which dates from the first centuries of church history. The teaching of Gnosticism questioned and/or contradicted the teaching of the church on some of the fundamental truths of Scripture. Apart from Gnosticism, the Early Church also had to deal with the heresy of Arianism. In the Nicene Creed, formulated by the councils of Nicea (325 AD and Constantinople (381 AD the universal or catholic church responded officially to the heresies of both Gnosticism and Arianism. In the final edition of the Nicene Creed we also find an article on the unity, holiness, catholicity and apostolicity of the church. Both Gnosticism and Arianism posed a serious threat to the unity of the church.   In our times we experience a revival of ancient Gnosticism, both pagan and “Christian”. This revival is also called the New Age or the Age of Aquarius. Within the framework of this new worldview, we are witnessing a rediscovery of gnosis. The discovery and publication of certain ancient gnostic texts like the Nag Hammadi Codices, play a significant role in this revival. Consequently the canon of Scripture is questioned or openly rejected and also the creeds based on that Scripture.   The Nicene Creed played a major and decisive role in preserving and maintaining the unity of the church on the basis of the truth of Scripture. This age-old creed is today just as relevant and important in proclaiming and confessing the true faith and preserving the true unity of the church.

The mystical Unity of Existence: A look at the philosophical interpretations of the mystics' view regarding The Unity vs. The plurality of existence

Directory of Open Access Journals (Sweden)

Agha Husain Shiraz

2017-01-01

Full Text Available The Unity of Existence is a concept that was first proposed by mystics. However, this concept has been interpreted in different ways by different groups of scholars. This is due to the fact that these mystics did not always speak in an explicit manner. One of the groups that attempted to interpret this concept was the philosophers. An examination of the works of philosophers leads to the conclusion that there are at least 15 different philosophical interpretations of the Unity of Existence. Some of these interpret this concept epistemologically, while others interpret it metaphysically. Some of them are legitimate interpretations of the sayings of the mystics, while others contradict some of the other sayings of the mystics and, therefore, cannot serve as adequate explanations of this mystical concept. Nonetheless, they can still serve as independent interpretations of the unity vs. multiplicity of the Universe. In this article, the 15 different philosophical interpretations of the mystical unity of existence will be presented and the legitimacy of some of them will be assessed. Another discussion that is of primary importance is the truth or falsehood of these interpretations. This is something that cannot be addressed in this article and, yet, deserves to be examined independently.

Unity-Based Diversity: System Approach to Defining Information

Directory of Open Access Journals (Sweden)

Yixin Zhong

2011-07-01

Full Text Available What is information? This is the first question that information science should answer clearly. However, the definitions of information have been so diversified that people are questioning if there is any unity among the diversity, leading to a suspicion on whether it is possible to establish a unified theory of information or not. To answer this question, a system approach to defining information is introduced in this paper. It is proved that the unity of information definitions can be maintained with this approach. As a by-product, an important concept, the information eco-system, was also achieved.

Unity and catholicity in the Korean Presbyterian Church: An ecumenical Reformed assessment

Directory of Open Access Journals (Sweden)

Jaegeon Ha

2016-03-01

Full Text Available I attempt to find the main causes of the serious disunity in the Presbyterian Church in Korea (PCK, which started as one church but is now divided into more than 100 denominations, as well as a solution to promote the unity of the PCK. This attempt starts with an exegesis of Ephesians, with special reference to Ephesians 4:1�16, to understand the biblical principle on this matter. This article draws on a mature ecclesiology and a mature sense of unity as key concepts. After that, the history of the PCK disunity is briefly described, dealing with four major schisms. Based on this historical investigation, the disunity in the PCK is assessed. In addition, the weak sense of unity and weak ecclesiology of the PCK, which played a role in its disunity, are discussed in view of the confessions of faith, the ministry of the word and the Lord�s Supper, and ecumenical efforts in relation to national and international ecumenical organisations. Lastly, contributory suggestions based on the mature sense of unity are offered to the PCK in particular and the Reformed family and all Christian churches in general.Intradisciplinary and/or interdisciplinary implications: In my ecumenical Reformed intradisciplinary assessment of unity and catholicity in the PCK, which started as one church but is now divided into more than 100 denominations, I identify the main causes of serious disunity in the PCK, namely a weak sense of unity, immaturity and secularisation.

Organic unity theory: an integrative mind-body theory for psychiatry.

Science.gov (United States)

Goodman, A

1997-12-01

The potential of psychiatry as an integrative science has been impeded by an internal schism that derives from the duality of mental and physical. Organic unity theory is proposed as a conceptual framework that brings together the terms of the mind-body duality in one coherent perspective. Organic unity theory is braided of three strands: identity, which describes the relationship between mentally described events and corresponding physically described events; continuity, which describes the linguistic-conceptual system that contains both mental and physical terms; and dialectic, which describes the relationship between the empirical way of knowing that is associated with the physical domain of the linguistic-conceptual system and the hermeneutic way of knowing that is associated with the mental domain. Each strand represents an integrative formulation that resolves an aspect of mental-physical dualism into an underlying unity. After the theory is presented, its implications for psychiatry are briefly considered.

Cosmonaut Yuri P. Gidzenko, Expedition One Soyuz commander, stands near the hatch leading from the Unity node into the newly-attached Destiny laboratory aboard the International Space Station (ISS). The Node 1, or Unity, serves as a cornecting passageway to Space Station modules. The U.S.-built Unity module was launched aboard the Orbiter Endeavour (STS-88 mission) on December 4, 1998, and connected to Zarya, the Russian-built Functional Cargo Block (FGB). The U.S. Laboratory (Destiny) module is the centerpiece of the ISS, where science experiments will be performed in the near-zero gravity in space. The Destiny Module was launched aboard the Space Shuttle Orbiter Atlantis (STS-98 mission) on February 7, 2001. The aluminum module is 8.5 meters (28 feet) long and 4.3 meters (14 feet) in diameter. The laboratory consists of three cylindrical sections and two endcones with hatches that will be mated to other station components. A 50.9-centimeter- (20-inch-) diameter window is located on one side of the center module segment. This pressurized module is designed to accommodate pressurized payloads. It has a capacity of 24 rack locations, and payload racks will occupy 13 locations especially designed to support experiments.

There is extensive uptake of ICT in the teaching of science and its impact on the learning, and considering the limited availability of laboratories for physics teaching and the difficulties this causes in the learning of school students, we design the virtual laboratories to enhance studentâĂŹs knowledge of concepts in physics. To achieve this goal, we use Unity due to provide support bump mapping, reflection mapping, parallax mapping, dynamics shadows using shadows maps, full-screen post-processing effects and render-to-texture. Unity can use the best variant for the current video hardware and, if none are compatible, to use an alternative shader that may sacrifice features for performance. The control over delivery to mobile devices, web browsers, consoles and desktops is the main reason Unity is the best option among the same kind cross-platform. Supported platforms include Android, Apple TV, Linux, iOS, Nintendo 3DS line, macOS, PlayStation 4, Windows Phone 8, Wii but also an asset server and Nvidia’s PhysX physics engine which is the most relevant tool on Unity for our PhysLab.

Theodor Waitz on psychic unity.

The tolerant stance on 'race' by prominent Enlightenment figures was followed in the 19th century by a powerful wave of biological racism. Many of its proponents took the view that human 'races' constitute separate species, and that most non-white ones are of inferior mentality. An early opponent of this claim was James Cowles Prichard, who used mainly missionary reports in seeking to refute it. Far more extensive work was undertaken by the Herbartian psychologist Theodor Waitz, who collected ethnographic material from all over the world. It was published in six volumes - the last two after his death by his former student Georg Gerland. Waitz aim was to demonstrate the 'psychic unity' of mankind. Initially extracts from the volume on African peoples are presented in order to show how he dealt with his material. The main focus is on his first volume entitled Introduction to Anthropology, in which he elaborates his general thesis. In it Waitz maintains, against the biological racists, that mankind is a single species. Furthermore he discusses the changes from savagery to civilization, attributing them to a combination of geography and history. He was followed by Adolf Bastian who, unlike Waitz, was a great traveller with personal experience of peoples all over the globe. Both firmly believed in the psychic unity of mankind, but Bastian's approach to psychology was very different.

Program unity in Parque Prazeres - Campos dos Goytacazes, RJ, and the level of patient's knowledge about diabetes visual impairment. METHODS: Seventy two diabetic patients were selected, but only 46 attended the research. The patients were chosen based on Family's Health Program medical registers. They were submitted to visual acuity examination and afterward to a questionnaire in order to evaluate their knowledge level about visual impairment. Then, they were submitted to a direct fundoscopic examination. Statistical studies were done based on Microsoft Excel and Bioestat 5.0 RESULTS: Diabetic retinopathy prevalence was about 19,5% (CI 95% between 8,1 and 31%; 13% showed non proliferative diabetic retinopathy and 6,5% showed proliferative retinopathy. In accordance with World Health's Organization criteria: 8,5% were considered blind and 8,9% with low vision at the moment of ocular examination. Seventy two percent of patients had previous knowledge that diabetes could cause visual reduction, but 80% didn't know the necessary exams to diagnose it and 65% never were previously submitted to ophthalmoscopy. CONCLUSION: Blindness prevention programs by diabetic retinopathy in Family Health Programs are justified considering that the retinopathy diabetic prevalence in assisted communities could be high, as was in this study. The improvement of patient knowledge about the vision threatening risk and ophthalmological exams can allow a better retinopathy diabetic control.

The concept of society’s organic unity and its representation in the historiosophy of Vladimir Soloviev and the early Slavophiles

Full Text Available The meaning of the concept of society’s organic unity has been investigated. This concept was an important part of Russian religious philosophy in the middle of the XIX century. It has been found that Schelling and Hegel idealistic philosophy and orthodox theology were the main sources of the concept of organic unity. The character and forms of the presentation of the organic unity’s concept in Vladimir Soloviev and the main representatives of early Slavophilism’s social philosophy and philosophy of history has been analyzed. By Solovyov, the subject of the historical development is mankind as holistic, organic phenomenon which tries to overcome the formal unity and to reach its spiritual level in the form of «God-manhood». Economic and legal unity is called the lowest form of unity by Solovyov, and the highest one, which reaches the organic and conscious level, is the spiritual unity. In the philosophy of Ivan Kireyevski, society’s organic unity is opposed to the formal, rational unity. The formal unity was inherited by Europe from ancient Rome. Cultural traditions of Greece and Orthodoxy were inherited by Slavs and saved the spiritual unity of society. According to Alexey Khomyakov, there are two contrasting models of culture: Iranian and Cushitic ones. Iranian model is based on freedom and conscious action. Iranian model creates a spiritual unity without suppression of individuals in society. Cushitic model creates a formal unity, it coercions and suppress individuals. The formality of the state association and the spiritual unity of the community have been opposed by Konstantin Aksakov. In tsarist Russia, all power was given to the monarch to protect the community. Therefore, Russia maintained an organic, internal unity of the people unlike Europe. In Europe, the state became stronger then the communities and state there suppressed communities. Rights and economy became to be more important than morality. European society became

Does John 17:11b, 21−23 refer to church unity?

Directory of Open Access Journals (Sweden)

Gert J. Malan

2011-04-01

Full Text Available In ecumenical circles, John 17:11b, 21–23 has been understood as Jesus’ prayer for church unity, be it confessional or structural. This article questioned such readings and conclusions from historical, literary and sosio-cultural viewpoints. The Fourth Gospel’s language is identified as ’antilanguage’ typical of an ’antisociety’, like that of the Hermetic, Mandean and Qumran sects. Such a society is a separate entity within society at large, but opposes it. Read as a text of an antisociety, John 17:11b, 21–23 legitimises the unity of the separatist Johannine community, which could have comprised several such communities. This community opposed the Judean religion, Gnosticism, the followers of John the Baptist and three major groups in early Christianity. As text from the canon, this Johannine text legitimates tolerance of diversity rather than the confessional or structural unity of the church.

IBN ‘ARABI AND THE TRANSCENDENTAL UNITY OF RELIGIONS

Full Text Available This essay describes Ibn ‘Arabi’s comprehensive views, captured in his important Futuhat and Fusus, on the concept of wahdat al-adyan, the discrepancy of beliefs, and the Shari’ah as well as its juncture and its unity. Elaborated explanation in this paper is expected to result in a true understanding of this crucial issue, particularly the concept of religious pluralism in the discourse of Islamic studies. Ibn Arabi’ extensively  discusses religion in the sense of the “ideal” versus “historical” or “esoteric” versus “the exoteric”. Ibn ‘Arabi concludes that the absolute unity of religions may only occur within spiritual, ideal, or transcendental realm (or “esoteric”, which is beyond the formal form of religions. Hence, the transcendental unity of religions cannot be found in the formal form of religions nor in the shari’ah.[Artikel ini mengulas pandangan Ibn ‘Arabi’ mengenai wahdat al-adyan seperti dijelaskan dalam dua bukunya; Futuhat dan Fusus, dan perbedaan dan kesamaan antara iman dan shariah. Diharapkan diskusi artikel ini berkontribusi dalam kajian pluralisme, utamanya dalam disiplin studi Islam. Dalam diskusinya, Ibn Arabi’  menjelaskan perbedaan ‘ideal’ dan ‘historikal’ atau antara ‘esoterik’ dan ‘eksoterik’. Ibn ‘Arabi berpendapat bahwa kemanunggalan agama-agama dapat dicapai melalui spiritualitas, ideal, atau dimensi transcendental (esoterik yang ada di luar tampilan formal agama-agama. Dengan kata lain, kemanunggalan tersebut tidak akan ditemukan pada shari’ah.

Hakim Mudarres Zunuzi and Banu Amin on the Unity of Essence A Comparative Study

2013-12-01

Full Text Available Tawhid (the belief in transcendent oneness or unity of divinity is the culmination of all Islamic teachings and has a special place in Islamic sciences. The unity of essence begins by the unity of existential necessity and ends in unity of existence as many theosophers and mystics suggest. This essay discusses unity of essence as understood by two Sadraean thinkers (Hakim Mudarres Zunuzi and Banu Amin according to Mulla Sadra's principles. Undoubtedly, these two theosophers have no discord as far as they speak about necessity of existence and unity of Necessary Existence. Dispute erupts when Banu voices her Sadraean sympathy with transcendent oneness of existence while Mudarres takes another position.       According to Sadra, the being which has no limitation whatsoever leaves no room for other being to come into existence and be its second or third and thus it is unique and uncountable. In this world, thus, there is no existence but one of which the rest are manifestations (Mulla Sadra, 1382, 67. This view which has been mentioned by Sadra in different positions is the very idea of individual unity of existence. It needs to be explained that in Mulla Sadra's works there are two accounts of effect: Existence in itself for something-else (relational existence Existence for something-else (copulative existence      At first sight which is thought to be elementary as compared to the second one, effect enjoys a reality and existence of its own the whole identity of which is though being related to and depended on cause and this dependency is its very essence and undetachable but the effect like the cause is counted among  beings. This is the position which is also held by Mudarres Zunuzi as to contingent beings (Mudarres Zunuzi, 1376: 357. He seem to have understood Mulla Sadra's words implying this very sense alone without presuming the possibility of a second sense. To put it otherwise, he has indeed fathomed effect's copulative

A single or multiphase boost chopper regulator operating with unity power factor, for use such as to charge a battery is comprised of a power section for converting single or multiphase line energy into recharge energy including a rectifier (10), one inductor (L.sub.1) and one chopper (Q.sub.1) for each chopper phase for presenting a load (battery) with a current output, and duty cycle control means (16) for each chopper to control the average inductor current over each period of the chopper, and a sensing and control section including means (20) for sensing at least one load parameter, means (22) for producing a current command signal as a function of said parameter, means (26) for producing a feedback signal as a function of said current command signal and the average rectifier voltage output over each period of the chopper, means (28) for sensing current through said inductor, means (18) for comparing said feedback signal with said sensed current to produce, in response to a difference, a control signal applied to the duty cycle control means, whereby the average inductor current is proportionate to the average rectifier voltage output over each period of the chopper, and instantaneous line current is thereby maintained proportionate to the instantaneous line voltage, thus achieving a unity power factor. The boost chopper is comprised of a plurality of converters connected in parallel and operated in staggered phase. For optimal harmonic suppression, the duty cycles of the switching converters are evenly spaced, and by negative coupling between pairs 180.degree. out-of-phase, peak currents through the switches can be reduced while reducing the inductor size and mass.

Body-self unity and self-esteem in patients with rheumatic diseases.

Science.gov (United States)

Bode, Christina; van der Heij, Anouk; Taal, Erik; van de Laar, Mart A F J

2010-12-01

Perceptions and evaluations of the own body are important sources of self-esteem. Having a rheumatic disease challenges maintenance of positive self-esteem due to consequences of the disease such as unfavorable sensations as pain and limited (physical) functioning. We expect that a positive experience of the own body in spite of a rheumatic disease (body-self harmony) will be associated with higher levels of self-esteem and that experiencing the body as unworthy part of the own person or as disabler for own strivings (body-self alienation) will result in lower levels of self-esteem. For this explorative study, the body experience questionnaire (BEQ) measuring body-self unity was developed and piloted. One hundred sixty-eight patients visiting the outpatient rheumatology clinic of the Medisch Spectrum Twente, Enschede, The Netherlands, completed a questionnaire on touchscreen computers to measure body-self unity (BEQ), illness cognitions (illness cognition questionnaire), pain intensity, functional limitations (health assessment questionnaire disability index), self-esteem (Rosenberg Self-Esteem Scale) and demographics. To analyze predictors of self-esteem, hierarchical regression analyses were employed. The BEQ revealed a two-factor structure with good reliability (subscale harmony, four items, Cronbach's α = 0.76; subscale alienation, six items, Cronbach's α = 0.84). The final model of the hierarchical regression analyses showed that self-esteem can be predicted by the illness cognitions helplessness and acceptance, by harmony and most strongly by alienation from the body. R(2) of the final model was 0.50. The relationship between functional limitations and self-esteem was totally mediated by the psychological constructs body-self unity and illness cognitions. This explorative study showed the importance of the unity of body and self for self-esteem in patients with a rheumatic disease.

Full Text Available The purpose of this paper is to show the methodological power and potentiality of the concept paradigm of unity introduced originally in the ceremony on the occasion of honoring Chiara Lubich with the doctor honoris causa title by the Catholic University of Lublin in 1996. Originally this conception was used to suggest the societal activity of Chiara Lubich in building, via the Focolari movement, psychosocial infrastructures for unity in various social domains, (for example in the economy of communion, in politics (politicians for unity project, in public media (journalists for unity, in ecumenism and inter-religious contacts (ecumenical and inter-religion Focolari Centers This conception is a kind of a great inspiration (a kind of Copernican revolution in the social sciences which would motivate the social sciences to build their own research paradigm of a type of mental and methodological power and potentiality which could give a new vision of social world (as Copernicus did in natural sciences (Biela, 1996, 2006. Thomas Kuhn (1962 regarded the Copernician revolution as the one which, in the history of science, best illustrates the nature of scientific revolution. The essence of paradigm in a Kuhnian sense is a mentality change in its nature. Copernicus had to change the well-established geocentric system which functioned not only in the science of his day but also in culture, tradition, social perception, and even in the mentality of religious and political authorities. And he did it in a well prepared empirical, methodological and psychological way.

Gleiser, Marcelo

2015-12-01

The essence of physical reality-what the world consists of-has been a heated focus of contention for millennia. First with philosophers and then with physicists, the debate has been polarized since the beginning: while those loosely known as Platonists search for an underlying unity in nature, others caution that such unity is unachievable in practice and in principle. In this essay, we review both positions, arguing strongly for the latter in anticipation of experimental results from the Large Hadron Collider, the particle accelerator from the European Center for Nuclear Research. We further argue that, for the first time in history, the material essence of reality could be determined from an empirical standpoint as opposed to a purely dialectic one, settling the age-old debate. © 2015 New York Academy of Sciences.

Effects of non-unity Lewis number of gas-phase species in turbulent nonpremixed sooting flames

KAUST Repository

Attili, Antonio

2016-02-13

Turbulence statistics from two three-dimensional direct numerical simulations of planar n-heptane/air turbulent jets are compared to assess the effect of the gas-phase species diffusion model on flame dynamics and soot formation. The Reynolds number based on the initial jet width and velocity is around 15, 000, corresponding to a Taylor scale Reynolds number in the range 100 ≤ Reλ ≤ 150. In one simulation, multicomponent transport based on a mixture-averaged approach is employed, while in the other the gas-phase species Lewis numbers are set equal to unity. The statistics of temperature and major species obtained with the mixture-averaged formulation are very similar to those in the unity Lewis number case. In both cases, the statistics of temperature are captured with remarkable accuracy by a laminar flamelet model with unity Lewis numbers. On the contrary, a flamelet with a mixture-averaged diffusion model, which corresponds to the model used in the multi-component diffusion three-dimensional DNS, produces significant differences with respect to the DNS results. The total mass of soot precursors decreases by 20-30% with the unity Lewis number approximation, and their distribution is more homogeneous in space and time. Due to the non-linearity of the soot growth rate with respect to the precursors\\' concentration, the soot mass yield decreases by a factor of two. Being strongly affected by coagulation, soot number density is not altered significantly if the unity Lewis number model is used rather than the mixture-averaged diffusion. The dominant role of turbulent transport over differential diffusion effects is expected to become more pronounced for higher Reynolds numbers. © 2016 The Combustion Institute.

The Meaning of Meeting as an Existential Event in the Perspective of the Unity Paradigm

Directory of Open Access Journals (Sweden)

Wąsiński Arkadiusz

2016-12-01

Full Text Available The article discusses the key meaning of meeting, understood as an existential event and considered in the perspective of the paradigm of unity. The two mentioned categories: meeting and paradigm of unity are not presented in the literature in the context of their direct relation to each other. Therefore, the main problem presented in the paper is: how far they are cognitively relevant. The starting point for reflections is the recognition of a meeting situation in the perspective of human spiritual development which happens through turning towards the other. This development is experienced in overcoming the tension between the declarative attitude towards the mutual love and the real act expressing the actual openness to this gift. According to Chiara Lubich, the gift of love is the central category of the paradigm of unity. If we follow Thomas Kuhn and define the paradigm as a worldview that unites a community in their holistic vision of the world, then it is the meeting that is an integral and necessary element of this paradigm. Experiencing a meeting, in this context, is the condition for reaching the spiritual unity in a community of people who are led by mutual love and out of that love bear with one another in their otherness.

Quantum groups, roots of unity and particles on quantized Anti-de Sitter space

International Nuclear Information System (INIS)

Steinacker, H.

1997-01-01

Quantum groups in general and the quantum Anti-de Sitter group U q (so(2,3)) in particular are studied from the point of view of quantum field theory. The author shows that if q is a suitable root of unity, there exist finite-dimensional, unitary representations corresponding to essentially all the classical one-particle representations with (half) integer spin, with the same structure at low energies as in the classical case. In the massless case for spin ≥ 1, open-quotes naiveclose quotes representations are unitarizable only after factoring out a subspace of open-quotes pure gaugesclose quotes, as classically. Unitary many-particle representations are defined, with the correct classical limit. Furthermore, the author identifies a remarkable element Q in the center of U q (g), which plays the role of a BRST operator in the case of U q (so(2,3)) at roots of unity, for any spin ≥ 1. The associated ghosts are an intrinsic part of the indecomposable representations. The author shows how to define an involution on algebras of creation and anihilation operators at roots of unity, in an example corresponding to non-identical particles. It is shown how nonabelian gauge fields appear naturally in this framework, without having to define connections on fiber bundles. Integration on Quantum Euclidean space and sphere and on Anti-de Sitter space is studied as well. The author gives a conjecture how Q can be used in general to analyze the structure of indecomposable representations, and to define a new, completely reducible associative (tensor) product of representations at roots of unity, which generalizes the standard open-quotes truncatedclose quotes tensor product as well as many-particle representations

Quantum groups in general and the quantum Anti-de Sitter group U_q(so(2,3)) in particular are studied from the point of view of quantum field theory. The author shows that if q is a suitable root of unity, there exist finite-dimensional, unitary representations corresponding to essentially all the classical one-particle representations with (half) integer spin, with the same structure at low energies as in the classical case. In the massless case for spin ≥ 1, "naive" representations are unitarizable only after factoring out a subspace of "pure gauges", as classically. Unitary many-particle representations are defined, with the correct classical limit. Furthermore, the author identifies a remarkable element Q in the center of U_q(g), which plays the role of a BRST operator in the case of U_q(so(2,3)) at roots of unity, for any spin ≥ 1. The associated ghosts are an intrinsic part of the indecomposable representations. The author shows how to define an involution on algebras of creation and anihilation operators at roots of unity, in an example corresponding to non-identical particles. It is shown how nonabelian gauge fields appear naturally in this framework, without having to define connections on fiber bundles. Integration on Quantum Euclidean space and sphere and on Anti-de Sitter space is studied as well. The author gives a conjecture how Q can be used in general to analyze the structure of indecomposable representations, and to define a new, completely reducible associative (tensor) product of representations at roots of unity, which generalizes the standard "truncated" tensor product as well as many-particle representations.

Variations in the prevalence of spondylolysis in early British populations.

Science.gov (United States)

Waldron, H A

1991-01-01

Crude prevalence rates of spondylolysis were estimated in skeletal populations from various periods. There was a steady increase in prevalence from 3.74% in Romano-British to 5.08% in medieval populations, but the rate fell considerably to 1.42% in a population from an 18th/19th century context. This trend was not statistically significant, however. The male/female ratio was approximately unity until the 18th/19th century when the expected male excess appeared. The lesions predominantly affected L5 and all were isthmic in type. Of the total of 52 cases, only four were unilateral. One occurred in the fourth cervical vertebra. There were few complications; spondylolisthesis was noted in four cases and in three there were osteoarthritic changes on the superior margin of the displaced lamina. PMID:1941859

THE ANTIQUE FOUNDATIONS FOR THE UNITY OF EDUCATION

Directory of Open Access Journals (Sweden)

Alexander E Krikunov

2017-12-01

Full Text Available The author of the paper considers the unity of education as a specific way of existence, blurring the distinction between ontological and anthropological interpretations of education. This approach is supposed to adequately identify the philosophic sense of the category of education without linking it exclusively to the philosophic consideration of educational practice. The author also points out the connection between the ideas of the world unity and of a human being’s education as a process of gradual approaching one’s true and complete image in the history of European philosophy. Even though the contemporary notion of education is most elaborately presented by classical German philosophers, the author aims to show the prospects of addressing the antique philosophic tradition proposing the first conceptualization of education connected with a special ontological position. The author calls attention to the gradual development of views on the systemic nature of being, linking it to the initial didactic guideline of Greek philosophers. The example of Aristotle’s ethics proves the integrity of externally separate ways of making up of a person. The author comes to a conclusion about the necessity of taking the connection of educational concepts and a characteristic tendency to create the philosophic theory of the world, the elements of which are united in an integrated system, into account. In the author’s opinion, it will allow to define the real philosophic and pedagogical sense of the revision of the classical philosophic tradition, undertaken by the contemporary philosophy.

How culture shapes community: bible belief, theological unity, and a sense of belonging in religious congregations.

Stroope, Samuel

2011-01-01

Feeling that you belong in a group is an important and powerful need. The ability to foster a sense of belonging can also determine whether groups survive. Organizational features of groups cultivate feelings of belonging, yet prior research fails to investigate the idea that belief systems also play a major role. Using multilevel data, this study finds that church members' traditional beliefs, group-level belief unity, and their interaction associate positively with members' sense of belonging. In fact, belief unity can be thought of as a “sacred canopy” under which the relationship between traditional beliefs and feelings of belonging thrives.

2000-05-01

A family of organically templated aluminophosphates (denoted AlPOs) with an Al/P ratio of non-unity has been prepared with 1-D chain, 2-D layer and 3-D open-framework architectures. Their inorganic parts are constructed from alternating Al-centered polyhedra (AlO 4, AlO 5, AlO 4(OH 2) 2) and P-centered tetrahedra P(OAl) nO 4- n ( n=0, 1, 2, 3). The existence of terminal POH and/or PO groups in the structures results in the deviation of Al/P ratio from unity, and the commonly encountered Al/P ratios are 1/2, 3/5, 2/3, 3/4, 4/5 and 5/6. This review will discuss the structural features of these AlPOs with various dimensionalities and stoichiometries.

Islamic Education With Multicultural Insight An Attempt Of Learning Unity In Diversity

Full Text Available Education has a vital role in smartening up human life; it is not surprising that the way to measure the quality of a civilization is determined by the quality of its educators. In the modern and heterogenic era as today, education with multicultural insight is required in order to give understanding about the importance of unity and diversity, so it is expected that there will be no more violence in the name of race, ethnicity, culture and even religion. Islam is often perceived as a harsh, exclusive and sectarian religion, whereas Islam is full of moral values, compassion, tolerance and inclusion. In response, Islamic education is required to give an understanding to the world that Islam is a religion that respects multiculturalism. This is where Islamic education with multicultural insight must be present in order to explain the relationship between man and God (hablun min Allah, theological aspects; the relationship of unity, namely human relationships with others (hablun min al-nas, anthropo-sociological aspects; and human relationship with the natural surroundings (hablun mi al-’Alam, cosmological aspect.

Yearning for the Lost Paradise: The "Great Unity" (datong and Its Philosophical Interpretations

2017-01-01

Full Text Available In the course of China’s history, the term datong (great unity has been interpreted in multiple ways. This article first discusses the concept as understood in the Liji, and then focuses on the way in which the perceived loss of the “great unity” within “all-under-heaven” (tianxia at the end of the Qing dynasty (1644–1911, and the endeavor to reconstruct the empire as a modern nation-state starting in the early twentieth century, informed the way the term datong was interpreted. After discussing the interpretations by Wang Tao (1828–1897, Hong Xiuquan (1813–1864, Kang Youwei (1858–1927, Liang Qichao (1873–1929, Sun Zhongshan (1866–1925, and Mao Zedong (1893–1976, this work concludes with a discussion on how, against the background of the perceived threat of loss of national unity that characterizes the contemporary People’s Republic of China, a New Confucian interpretation is developed.

Inseparability of Go and Stop in Inhibitory Control: Go Stimulus Discriminability Affects Stopping Behavior.

Science.gov (United States)

Ma, Ning; Yu, Angela J

2016-01-01

Inhibitory control, the ability to stop or modify preplanned actions under changing task conditions, is an important component of cognitive functions. Two lines of models of inhibitory control have previously been proposed for human response in the classical stop-signal task, in which subjects must inhibit a default go response upon presentation of an infrequent stop signal: (1) the race model, which posits two independent go and stop processes that race to determine the behavioral outcome, go or stop; and (2) an optimal decision-making model, which posits that observers decides whether and when to go based on continually (Bayesian) updated information about both the go and stop stimuli. In this work, we probe the relationship between go and stop processing by explicitly manipulating the discrimination difficulty of the go stimulus. While the race model assumes the go and stop processes are independent, and therefore go stimulus discriminability should not affect the stop stimulus processing, we simulate the optimal model to show that it predicts harder go discrimination should result in longer go reaction time (RT), lower stop error rate, as well as faster stop-signal RT. We then present novel behavioral data that validate these model predictions. The results thus favor a fundamentally inseparable account of go and stop processing, in a manner consistent with the optimal model, and contradicting the independence assumption of the race model. More broadly, our findings contribute to the growing evidence that the computations underlying inhibitory control are systematically modulated by cognitive influences in a Bayes-optimal manner, thus opening new avenues for interpreting neural responses underlying inhibitory control.

The Unity-Of-Value as a Theory of Interpretation

2016-12-01

Full Text Available This paper aims to address the unity of value as a general theory of interpretation. By overcoming the supposed division between law and morality, considering the interpretive activity the central element of a normative theory of all human endeavor, Dworkin highlights the limitations of legal positivism designed by Hart to provide adequate solutions to the "hard cases" and broadens the spectrum to find a "correct answer" to specific cases in a normative theory linked to political morality, expressed by the interpretive activity, whose meaning will be the value assigned by the interpreter to a particular event or object.

Two-rowed Hecke algebra representations at roots of unity

The explicit construction of irreducible representations of the Hecke algebra H n (q) of type A n-1 was studied for the non-generic case where q is a root of unity. The approach is via the Specht modules of H n (q) which are irreducible in the generic case and possess a natural basis indexed by Young tableaux. The general framework in which the non-generic H n (q)-modules are to be constructed is set up and, in particular, the full set of modules corresponding to two-part partitions is described. Many examples are given. 12 refs

Full Text Available Witkacy’s Pure Form expresses the metaphysical essence of art. On the one side, it symbolizes the structure of the world, the unity in plurality (which is demonstrated in the picture’s composition and, on the other, the notion deals with the processes of creating and perceiving an art work. The moment in which the self feels itself embedded in the wholeness of the world is the moment in which the metaphysical feeling arises, and in which the experience of art is fulfilled. Witkacy provides many examples for situations evoking this feeling. He describes them in his novels, he finds synonyms as suchness, curiosity of existence, mystery of being or unity of identity, he switches from scientific to poetic language. And he emphasizes that this feeling, while defying verbalization, is a real, not a supernatural one: a psychophysical phenomenon accessible to introspection, and inseparable from one's cultural and individual background.

Amyloid precursor protein and endosomal-lysosomal dysfunction in Alzheimer's disease: inseparable partners in a multifactorial disease.

Science.gov (United States)

Nixon, Ralph A

2017-07-01

Abnormalities of the endosomal-lysosomal network (ELN) are a signature feature of Alzheimer's disease (AD). These include the earliest known cytopathology that is specific to AD and that affects endosomes and induces the progressive failure of lysosomes, each of which are directly linked by distinct mechanisms to neurodegeneration. The origins of ELN dysfunction and β-amyloidogenesis closely overlap, which reflects their common genetic basis, the established early involvement of endosomes and lysosomes in amyloid precursor protein (APP) processing and clearance, and the pathologic effect of certain APP metabolites on ELN functions. Genes that promote β-amyloidogenesis in AD (APP, PSEN1/2, and APOE4) have primary effects on ELN function. The importance of primary ELN dysfunction to pathogenesis is underscored by the mutations in more than 35 ELN-related genes that, thus far, are known to cause familial neurodegenerative diseases even though different pathogenic proteins may be involved. In this article, I discuss growing evidence that implicates AD gene-driven ELN disruptions as not only the antecedent pathobiology that underlies β-amyloidogenesis but also as the essential partner with APP and its metabolites that drive the development of AD, including tauopathy, synaptic dysfunction, and neurodegeneration. The striking amelioration of diverse deficits in animal AD models by remediating ELN dysfunction further supports a need to integrate APP and ELN relationships, including the role of amyloid-β, into a broader conceptual framework of how AD arises, progresses, and may be effectively therapeutically targeted.-Nixon, R.

Utilizing Bourdieu's concept of the habitus, Keith Macdonald has recently examined the elite social origins of the British officer corps. His analysis is valid as far at it goes but it ignores the professional practices of British officers. This article examines Britain's Joint Services Command and Staff College to assess the unification of the three services around common forms of military practice. It argues that while the new staff college has been effective in disseminating new forms of professional expertise among British officers, various practices have been institutionalized which actively undermine the unity of the officer corps.

Full Text Available This paper represents the outcome of research fellowship Marie Curie at the Universiteit Leiden -Campud Den Haag Grotius, Centre for International Legal Studies (prof. C. Stahn and prof. Larissa van den Herik, supervisors on the topic "The Fragmentation and the Diversification of International Criminal Law in a Global Society”.In my paper I will examine the question of whether Universal Jurisdiction (UJ leads to unity or fragmentation within International Criminal Law (ICL. Given that there is already quite a lot of literature on UJ, it is important to focus the research on the issue of fragmentation and/or unity rather than to deal with the issue of UJ more generally. I will focus on this topic in sections 1 and 2, explaining some cursory remarks to these issues in my analysis on fragmentation. In the introduction, I will briefly introduce UJ as a controversial form of jurisdiction, but still necessary given that territorial jurisdiction does not always function well in the case of international crime. I will demonstrate that many state parties to the International Criminal Court (ICC Statute have vested or reconfirmed UJ for the core crimes when implementing the ICC Statute. The leading question of my research is whether this practice has led or has the potential to lead to unity or rather to fragmentation within ICL. In the research I will approach this question from different perspectives.In section 1 I will examine how State parties have may actually enacted universal jurisdiction for the core crimes, with a view to determining whether there is indeed some unity on this front or whether the practice on this matter is actually rather diverse (or fragmented. Subsequently, I will analyse which conditions States have formulated for the exercise of UJ, and whether this practice is consistent (unity or again rather diverse (fragmentation. It might also be interesting to see whether States have different conditions for UJ over core crimes than

A NOVEL THREE PHASE UNITY POWER FACTOR CONVERTER

Directory of Open Access Journals (Sweden)

Bekir Sami SAZAK

1998-03-01

Full Text Available The proposed unity power factor converter system which is able to operate from a 150V three-phase supply whilst delivering the required 200V DC voltage has been built and tested. This circuit functions as a high power factor low harmonic rectifier based on the concept that the peak capacitor voltages are proportional to the line input currents. Hence the low frequency components of the capacitor voltages are also approximately proportional to the line input currents. The system can be designed to achieve nearly sinusoidal supply input currents, when operated with discontinuous resonant capacitor voltages Output power control is achieved by variations of the IGBTs switching frequency. The converter is therefore able to compensate for any changes in the load resistance. The proposed topology offers advantages, including: a relatively simple power, control and protection circuits, high power capability, and high converter efficiencies.

Direct numerical simulations of temporally developing hydrocarbon shear flames at elevated pressure: effects of the equation of state and the unity Lewis number assumption

Science.gov (United States)

Korucu, Ayse; Miller, Richard

2016-11-01

Direct numerical simulations (DNS) of temporally developing shear flames are used to investigate both equation of state (EOS) and unity-Lewis (Le) number assumption effects in hydrocarbon flames at elevated pressure. A reduced Kerosene / Air mechanism including a semi-global soot formation/oxidation model is used to study soot formation/oxidation processes in a temporarlly developing hydrocarbon shear flame operating at both atmospheric and elevated pressures for the cubic Peng-Robinson real fluid EOS. Results are compared to simulations using the ideal gas law (IGL). The results show that while the unity-Le number assumption with the IGL EOS under-predicts the flame temperature for all pressures, with the real fluid EOS it under-predicts the flame temperature for 1 and 35 atm and over-predicts the rest. The soot mass fraction, Ys, is only under-predicted for the 1 atm flame for both IGL and real gas fluid EOS models. While Ys is over-predicted for elevated pressures with IGL EOS, for the real gas EOS Ys's predictions are similar to results using a non-unity Le model derived from non-equilibrium thermodynamics and real diffusivities. Adopting the unity Le assumption is shown to cause misprediction of Ys, the flame temperature, and the mass fractions of CO, H and OH.

Full Text Available This descriptive-analytic study by method in the form of a library in the field of Sciences of Quran and Hadith and suggests a new theory on difference of views about the religious judgments. The main problem is in one hand, the Quran's recognition of the plurality of religions in some verses and in other hand,the other verses those can be seen on the negation of religious plurality. In light of certain verses in this issue, some of thinkers have raised under different titles such as Traditionalism or religious pluralism and the unity of religions and religious pluralism and so on. mentioned religions in Quran, are essentially same in the Islam and monotheism. Thus there are the consensus on essential unity of religions and disagreement onhistoric unity of religions that is a source of more disagreements and different issues. Quran has determined the "bestdispute" asa method of dealing with religious laws that requires faith to common elements that is the "Islam" , although the "bestdispute" in light of the transcendental unity. This means that "best dispute" is a line between practical and theoretical pluralism. Instead of denying the "people of the Book", you shouldtake "Astbqa on charity" or overtaking on virtues. The rule stated in the Qur'an can be call"penetration in religion" and through this we can have better understand of the Qur'an's emphasis on reinforcement the Torah and the Gospel. However It should not be as pluralists, we have means Islam as only a religion in other religions.according to the Qur'an, the Prophet is the witness of the Muslims and people of Islam are witnesses of other peoples. total of true and mystical interpretation of the verses with these verses that explain Muslim religious superiorityindicate that the teachings of Islam has started fromthe holy scriptures, but under the prestige and the testimony of the teachings of the Prophet can be searched. In the Quran, the Muslim community have been called "moderate

Full Text Available The unity theme as it is found in John 17 and in IQS I-IX provides sufficient comparative material to give an indication of the extent to which John�s theology flourished within the contemporary Jewish context. It is argued that the events surrounding Christ constituted for John the central point of orientation according to which the typical Jewish ideas could be interpreted and reformulated. It is finally concluded that, according to this radical and exclusive Christian dynamic approach, certain elements within Judaism, also found among members of the Qumran community, were reinterpreted, while others were either continued or discontinued.

A linear polarization converter with near unity efficiency in microwave regime

Science.gov (United States)

Xu, Peng; Wang, Shen-Yun; Geyi, Wen

2017-04-01

In this paper, we present a linear polarization converter in the reflective mode with near unity conversion efficiency. The converter is designed in an array form on the basis of a pair of orthogonally arranged three-dimensional split-loop resonators sharing a common terminal coaxial port and a continuous metallic ground slab. It converts the linearly polarized incident electromagnetic wave at resonance to its orthogonal counterpart upon the reflection mode. The conversion mechanism is explained by an equivalent circuit model, and the conversion efficiency can be tuned by changing the impedance of the terminal port. Such a scheme of the linear polarization converter has potential applications in microwave communications, remote sensing, and imaging.

Full Text Available The article examines the phenomenon of corporatism, which under the adverse external environment can be used by the professional community to improve the effectiveness of organization. The authors define corporatism of the professional society as a combination of homogenous interests, attitudes, traditions and values; and provide a sociological interpretation of the corporate unity through its organizational and behavioral parameters. The former consists of the perception of the organization reliability, the staff’s confidence in the future, satisfaction with the financial situation (static features, estimates of the innovative capabilities of the company, and the willingness to develop (dynamic features. The behavioral parameters include staff’s values and patterns of behavior that can contribute to the consolidation of the professional community. The authors believe that for corporate management vertical social ties are less important that the horizontal ones, such as the rule of law and honesty, and the team unity under the unstable external environment. The sample of the study conducted by the authors in 2015 consisted of various types of settlements typical for the Sverdlovsk Region: mono-towns and mono-settlements (Nizhny Tagil, Serov, towns and villages with the differentiated economic activities (Ekaterinburg, Irbit. The results of the empirical study of corporatism among different professional societies - industrial workers, social services’ and business organizations’ staff, individual entrepreneurs and authorities - revealed the internal resources that can reduce tensions on the labor market. The research data can be useful for the comparative analysis of corporatism in different regions of Russia (not only industrial and similar to the Ural Region, but differing from it by significant social and economic parameters.

Sustainability Science as a Transdisciplinary Framework for Institutional Transformation at Unity College

Science.gov (United States)

Mulkey, S. S.

2012-12-01

Interdisciplinary programming in higher education is accepted as necessary for effective instructional delivery of complex environmental problems. Difficulties in sharing resources among disciplinary units and the need for students to sequentially access information from different disciplines limit the effectiveness of this approach. In contrast, transdisciplinary programming requires that the perspectives of various disciplines be simultaneously integrated in problem-focused pedagogy. Unity College, an environmental college in Maine, has recently adopted Sustainability Science (sensu U.S. National Academy of Science) as a framework for transdisciplinary pedagogy throughout all of its degree programs. Sustainability Science is a promising alternative framework that focuses on the dynamics of coupled human-natural systems and is defined by the problems that it addresses rather than by the disciplines it employs. Students are empowered to become brokers of knowledge, while faculty perform a curatorial role to provide students with networked resources generally external to the classroom. Although the transdisciplinary framework is effective for delivery of Sustainability Science in upper division and capstone courses, we propose this approach also for elements of our general education curriculum during the first two years of our baccalaureate programs. Classroom time is liberated for experiential student engagement and recitation. Our experience suggests that transdisciplinary programming can provide students with critical thinking skills and thus enhance the postgraduate value of their baccalaureate degree. We are coordinating the development of this distinctive curriculum delivery with a marketing program that will make Unity College accessible to a wider range of clientele. Our implementation of transdisciplinary programming will occur over a four-year period and requires explicit and fundamental change in essentially all aspects of College administration and

A kinetic model of droplet heating and evaporation: Effects of inelastic collisions and a non-unity evaporation coefficient

KAUST Repository

Sazhin, Sergei S.

2013-01-01

The previously developed kinetic model for droplet heating and evaporation into a high pressure air is generalised to take into account the combined effects of inelastic collisions between molecules in the kinetic region, a non-unity evaporation coefficient and temperature gradient inside droplets. It is pointed out that for the parameters typical for Diesel engine-like conditions, the heat flux in the kinetic region is a linear function of the vapour temperature at the outer boundary of this region, but practically does not depend on vapour density at this boundary for all models, including and not including the effects of inelastic collisions, and including and not including the effects of a non-unity evaporation coefficient. For any given temperature at the outer boundary of the kinetic region the values of the heat flux are shown to decrease with increasing numbers of internal degrees of freedom of the molecules. The rate of this decrease is strong for small numbers of these degrees of freedom but negligible when the number of these degrees exceeds 20. This allows us to restrict the analysis to the first 20 arbitrarily chosen degrees of freedom of n-dodecane molecules when considering the effects of inelastic collisions. The mass flux at this boundary decreases almost linearly with increasing vapour density at the same location for all above-mentioned models. For any given vapour density at the outer boundary of the kinetic region the values of the mass flux are smaller for the model, taking into account the contribution of internal degrees of freedom, than for the model ignoring these degrees of freedom. It is shown that the effects of inelastic collisions lead to stronger increase in the predicted droplet evaporation time in Diesel engine-like conditions relative to the hydrodynamic model, compared with the similar increase predicted by the kinetic model considering only elastic collisions. The effects of a non-unity evaporation coefficient are shown to be

An optoelectric professional's training model based on Unity of Knowing and Doing theory

Science.gov (United States)

Qin, Shiqiao; Wu, Wei; Zheng, Jiaxing; Wang, Xingshu; Zhao, Yingwei

2017-08-01

The "Unity of Knowing and Doing" (UKD) theory is proposed by an ancient Chinese philosopher, Wang Shouren, in 1508, which explains how to unify knowledge and practice. Different from the Chinese traditional UKD theory, the international higher education usually treats knowledge and practice as independent, and puts more emphasis on knowledge. Oriented from the UKD theory, the College of Opto-electric Science and Engineering (COESE) at National University of Defense Technology (NUDT) explores a novel training model in cultivating opto-electric professionals from the aspects of classroom teaching, practice experiment, system experiment, design experiment, research experiment and innovation experiment (CPSDRI). This model aims at promoting the unity of knowledge and practice, takes how to improve the students' capability as the main concern and tries to enhance the progress from cognition to professional action competence. It contains two hierarchies: cognition (CPS) and action competence (DRI). In the cognition hierarchy, students will focus on learning and mastering the professional knowledge of optics, opto-electric technology, laser, computer, electronics and machine through classroom teaching, practice experiment and system experiment (CPS). Great attention will be paid to case teaching, which links knowledge with practice. In the action competence hierarchy, emphasis will be placed on promoting students' capability of using knowledge to solve practical problems through design experiment, research experiment and innovation experiment (DRI). In this model, knowledge is divided into different modules and capability is cultivated on different levels. It combines classroom teaching and experimental teaching in a synergetic way and unifies cognition and practice, which is a valuable reference to the opto-electric undergraduate professionals' cultivation.

Full Text Available For starting a long term programmes in Croatian animal production, formation of "economic unities" is necessary. Presentation and explanation of production and trade unity for animal production and marketing with subjects and phases is given here. It is pointed out that production of slaughter animals and meat is key interest of market and economic policy as well as of development of agricultural country. It seems that production and trade of meat in Croatia is not organized enough in overall market competition and in meat processing. Creating the economic unity of production and trade of slaughter animals can help in relative fast and efficient solving of problems accumulated in agriculture, especialy in meat production (PIK Vrbovec, Danica, Bejle etc. For initiating and getting in function the phases of production and trade of slaughter animals and meat, proper legislation should be introduced. This legislation should comprehencively define the idea of agricultural economy as a subject of legislative and normisation acts for overall, process and market oriented functioning of multidisciplinary agricultural systems. Additionaly, law on trade of slaughter animals, meat and agricultural products should be introduced in order to form a market and determine the share and obligations of certain participants in structure of such market.

Full Text Available It is undeniable that the European Union represents the most ambitious legal and linguistic project, integrating 28 Member States and 24 official languages. What we undertook with this study was to explore the importance of multilingualism in the European Union and the problems that unity in diversity involves. This study tried to touch upon both theoretical aspects (i.e., what the multilingualism of EU law implies and practical issues (i.e., the interaction between legal languages at national and at EU level, problems emerging from multilingualism, illustrated by the relevant case law of the European Court of Justice. In many ECJ cases, it was underlined that multilingualism is essential to the EU legal order. The meaning of EU law cannot be derived from one version of the official languages and the ECJ regularly heads for a uniform interpretation of the contradictory versions. The present study is part of a more complex research on this theme and it is meant to approach certain important points of my PhD thesis. A first part of this research on multilingualism has already been published.

Full Text Available This is the text around the themes: Media and Journalism, are confronted two directions of opinions: humanism and elitism. Humanism believes that media and journalism must be metaphysically objective: able to tell the truth regardless of time, place and terms of events. Another approach, elitism, is connected with Hegel's philosophy of history. Hegel's conceptual apparatus includes: Idea, History dialectic, 'cunning mind,' self- development and self-realization. In this context, media and journalism are considered as organic unity, an inseparable part of some dialectical totality. More specifically media and journalism can be objective only if they defend concrete ideological assumptions of society to which they belong. Any other understanding of these two concepts is non-objective, mere moralizing and / or demagoguery.

Calculating Solar Energy Potential of Buildings and Visualization Within Unity 3d Game Engine

Solar energy modelling is increasingly popular, important, and economic significant in solving energy crisis for big cities. It is a clean and renewable resource of energy that can be utilized to accommodate individual or group of buildings electrical power as well as for indoor heating. Implementing photovoltaic system (PV) in urban areas is one of the best options to solve power crisis over expansion of urban and the growth of population. However, as the spaces for solar panel installation in cities are getting limited nowadays, the available strategic options are only at the rooftop and façade of the building. Thus, accurate information and selecting building with the highest potential solar energy amount collected is essential in energy planning, environmental conservation, and sustainable development of the city. Estimating the solar energy/radiation from rooftop and facade are indeed having a limitation - the shadows from other neighbouring buildings. The implementation of this solar estimation project for Istanbul uses CityGML LoD2-LoD3. The model and analyses were carried out using Unity 3D Game engine with development of several customized tools and functionalities. The results show the estimation of potential solar energy received for the whole area per day, week, month and year thus decision for installing the solar panel could be made. We strongly believe the Unity game engine platform could be utilized for near future 3D mapping visualization purposes.

Some Thoughts about Literature as a Means of Advancing Sustainable Unity and Stability in the Contemporary Nigerian State

Anaso George Nwaorah

2014-06-01

Full Text Available An in depth investigation was conducted on the possibility of literature employed to enhance cohesion, sustainable unity, national stability and security of lives and property in the contemporary Nigeria. These three elements- Unity, national stability and security of lives and property are considered the key-pillars of a modern state, the absence of which render the Country volatile and uninhabitable. The contemporary Nigeria lacks these elements in a large dose, thereby rendering it a country without peace and security. This has been the root cause of the current nationwide agitation for a national conference required to define the future for a country that has existed for a century, but still grappling unsuccessfully, with the problems of nationhood. This paper identified the cause of the problems to arise from the multi-ethnic composition of the one-hundred and seventy million people and over three hundred different ethnic nationals of Nigeria. The fact of uniting so many ethnic groups into one country is not peculiar to Nigeria, as many other countries have a similar composition.

Application of the Unity Rockfall Model to Variable Surface Material Conditions

Sala, Zac; Hutchinson, D. Jean; Ondercin, Matthew

2017-04-01

Rockfall is a geological process that poses risks to the safe operation of transportation infrastructure in mountainous environments world wide. The Unity rockfall model was created as a tool for 3D rockfall simulation as part of the Railway Ground Hazards Research Program, studying the impact of geotechnical hazards affecting Canadian railways [1]. The Unity rockfall model demonstrates the applicability of 3D video game engines for the development of realistic simulations, leveraging high-resolution site data collected using remote sensing techniques. Currently work is being done to further calibrate the model as an engineering tool for decision support. Calibration datasets include high-resolution terrestrial LiDAR and helicopter photogrammetry data collected as part of an ongoing rockfall monitoring program along the Thompson River Valley in south-central British Columbia, Canada. Change detection techniques developed as part of the program have been used to construct a database of rockfall event history and to develop magnitude-frequency relationships for rockfalls in the area [2][3]. Data collected as part of a controlled rock-rolling field program in Christchurch, New Zealand [4] is also being utilized for model calibration. Data on block dynamics for the artificially triggered rockfalls were collected through the use of embedded motion sensors and a sixteen camera setup. These experiments provide detailed information on block kinematics, and capture each impact point of the rockfall with the slope, thus offering a valuable dataset for comparison with modelling results. The research reported here explores the ability of the game engine based modelling technique to simulate rockfall under the variable slope conditions present at each of the sites where calibration data was collected. This includes steep natural rock slopes, with debris-talus cover, as well as shallower slopes with soil cover and vegetation. The varying slope conditions in each environment

A unified computational model of the development of object unity, object permanence, and occluded object trajectory perception.

Science.gov (United States)

Franz, A; Triesch, J

2010-12-01

The perception of the unity of objects, their permanence when out of sight, and the ability to perceive continuous object trajectories even during occlusion belong to the first and most important capacities that infants have to acquire. Despite much research a unified model of the development of these abilities is still missing. Here we make an attempt to provide such a unified model. We present a recurrent artificial neural network that learns to predict the motion of stimuli occluding each other and that develops representations of occluded object parts. It represents completely occluded, moving objects for several time steps and successfully predicts their reappearance after occlusion. This framework allows us to account for a broad range of experimental data. Specifically, the model explains how the perception of object unity develops, the role of the width of the occluders, and it also accounts for differences between data for moving and stationary stimuli. We demonstrate that these abilities can be acquired by learning to predict the sensory input. The model makes specific predictions and provides a unifying framework that has the potential to be extended to other visual event categories. Copyright © 2010 Elsevier Inc. All rights reserved.

2017-11-01

A new two dimensional Diagonal Eigenvalue Unity (2D-DEU) code is developed for the spectral⧹spatial optical code division multiple access (OCDMA) system. It has a lower cross correlation value compared to two dimensional diluted perfect difference (2D-DPD), two dimensional Extended Enhanced Double Weight (2D-Extended-EDW) codes. Also, for the same code length, the number of users can be generated by the 2D-DEU code is higher than that provided by the others codes. The Bit Error Rate (BER) numerical analysis is developed by considering the effects of shot noise, phase induced intensity noise (PIIN), and thermal noise. The main result shows that BER is strongly affected by PIIN for the higher source power. The 2D-DEU code performance is compared with 2D-DPD, 2D-Extended-EDW and two dimensional multi-diagonals (2D-MD) codes. This comparison proves that the proposed 2D-DEU system outperforms the related codes.

To generate a substantive grounded theory of relatives' pattern of behaviour in older patients' fast-track treatment programmes during total hip or knee replacement. Fast-track treatment programmes are designed to make total hip and knee replacements more efficient through recovery improvements. The support of relatives during older patients' trajectory is important. However, knowledge is needed on the relatives' pattern of behaviour to strengthen their involvement in fast-track treatment programmes. We used a Glaserian grounded theory approach based on a systematic generation of theory from data to explain the latent pattern of behaviour of relatives. Data were collected from 2010-2011 in orthopaedic wards at two Danish university hospitals and consisted of 14 non-participant observations, 14 postobservational interviews and five interviews. Seven relatives of patients over 70 years of age participated. The constant comparative method was the guiding principle for simultaneous data collection, data analysis and coding, while theoretically sampling and writing memos. Maintaining Unity emerged as the relatives' pattern of behaviour through which they resolved their main concern: preventing the patients from feeling alone. The relatives resolved their main concern through three interchangeable behavioural modes: Protecting Mode, by providing loving and respectful support; Substituting Mode, with practical and cognitive support; and an Adapting Mode, by trying to fit in with the patients' and health professionals' requirements. The substantive theory of Maintaining Unity offers knowledge of relatives' strong desire to provide compassionate and loving support for the older patients during fast-track treatment programmes. © 2014 John Wiley & Sons Ltd.

Emittance of a finite scattering medium with refractive index greater than unity

International Nuclear Information System (INIS)

Crosbie, A.L.

1980-01-01

Refractive index and scattering can significantly influence the transfer of radiation in a semitransparent medium such as water, glass, plastics, or ceramics. In a recent article (1979), the author presented exact numerical results for the emittance of a semiinfinite scattering medium with a refractive index greater than unity. The present investigation extends the analysis to a finite medium. The physical situation consists of a finite planar layer. The isothermal layer emits, absorbs, and isotropically scatters thermal radiation. It is characterized by single scattering albedo, optical thickness, refractive index, and temperature. A formula for the directional emittance is derived, the directional emittance being the emittance of the medium multiplied by the interface transmittance. The ratio of hemispherical to normal emittance is tabulated and discussed

Suppose we are given an entangled pair and asked how well we can produce two entangled pairs starting from a given entangled pair using only local operations. To respond to this question, we study broadcasting of entanglement using a state-dependent quantum cloning machine as a local copier. We show that the length of the interval for probability-amplitude-squared α 2 for broadcasting of entanglement using a state-dependent cloner can be made larger than the length of the interval for probability-amplitude-squared for broadcasting entanglement using a state-independent cloner. Further we show that there exists a local state-dependent cloner which gives better quality copy (in terms of average fidelity) of an entangled pair than the local universal cloner

Noyes, Matthew A.

2013-01-01

This paper explores low-cost hardware and software methods to provide depth cues traditionally absent in monocular displays. The use of a VRPN server in conjunction with a Microsoft Kinect and/or Nintendo Wiimote to provide head tracking information to a Unity application, and NVIDIA 3D Vision for retinal disparity support, is discussed. Methods are suggested to implement this technology with NASA's EDGE simulation graphics package, along with potential caveats. Finally, future applications of this technology to astronaut crew training, particularly when combined with an omnidirectional treadmill for virtual locomotion and NASA's ARGOS system for reduced gravity simulation, are discussed.

A model for monitoring catalyst mass flow in riser of Fluid Catalytic Cracking - FCC, pilot unity as a function of air flow and solid injection is proposed. The fluidized FCC- catalyst bed system is investigated in an experimental setup the Cold Pilot Unity - CPU by means of gamma ray transmission measurements. Riser in CPU simulates the reactor in FCC process. By automation control air flow is instrumentally measured in riser and the solid injection is manually controlled by valve adjusting. Keeping a constant solid injection, catalyst level at the return column was measured by gamma transmission for several air flow values in riser. The operational condition reached a steady state regime before given to setup a new air flow value. A calibration of catalyst level as a function of air flow in riser is calculated, therefore, a model for solid feed rate is derived. Recent published work evaluates solid concentration in riser of the CPU by means of gamma ray transmission, and a correlation with air velocity is obtained. In this work, the model for solid feed rate was further investigated by carrying out experiments to measure catalyst concentration at the same air flow values. These experiments lead to a model for monitoring catalyst flow in riser as function of solid feed rate and air flow. Simulation with random numbers produced with Matlab software allows to define validation criteria for the model parameters. (author)

Anticipation: learning from the past. The Russian/Soviet contributions to the science of anticipation

Science.gov (United States)

Bazac, Ana

2018-05-01

The focus on Russian/Soviet contributions is only an opportunity to understand the objective premises of anticipation. Since anticipation expresses a main concept characterizing human action, it is important to see whether and how it corresponds to the neuro-physiology of the human. The aim of this review is to show that anticipation is neuro-physiologically constitutive and is intertwined with all other reflective, cognitive, and coordinative functions that form an inseparable unity in the process of adaptation. The experiments described in the book draw attention to anticipation as the internal tendency of the living that cannot be ignored. The review highlights the dialectic of continuity and discontinuity in the living from the standpoint of anticipation, and the holistic conclusions of the scientific research regarding the living and the human being.

The Paradigm of Unity in Prenatal Education and Pedagogy

Kornas-Biela Dorota

2014-07-01

Full Text Available The traditional approach to the relation between parents and their prenatal child presents the child as a fetus, a mainly passive recipient of the mother’s vital biological resources. Contemporary prenatal psychology and pedagogy recognizes this relationship in a quite different perspective: the prenatal child is a member of the family and may be seen as an active member of the wider family as a community, extended to grandparents and other relatives. Between parents and their child in the womb exists a reciprocal relationship at a physiological (hormonal, psychological and spiritual level. The prenatal child communicates with the parents in different ways and reacts to their stimulation (acoustic, tactile, loco-motoric, chemo-receptive, thermo-receptive, and emotional. This dialogue of the parents and their prenatal child enriches each member of the family community. In this sense, the prenatal child is a gift and a challenge for the parents to develop their personality, social competences and spiritual life. The reflections presented in this paper fit the conception of the paradigm of unity applied into the area of prenatal education and prenatal pedagogy as a new pedagogical subdisciline.

Theological theses on the ethics of organ transplantation and on a law concerning the transplantation.

Science.gov (United States)

Jörns, K P

1994-12-16

The message of the resurrection from the dead is relevant to human beings living and dying in the unity of body and soul. The personality of man is inseparable connected with this unit--even beyond death. Brain death only marks a (decisive) point during the process of dying, and it cannot be defined as the death of a human being (in general). Theological ethics object to this definition and to a new dualism of brain and body as well as of body and personality (i.e. soul), because this dualism socialises the organs of individuals and denies the personal dignity of disappearing life. Therefore, the explantation of organs must depend on a personal declaration of consent given by the adult sponsor himself. Each information given on organ transplants must clarify that the explanation of organs means an interruption of dying.

The canon of pure reason: Kant on the non-dependent establishment of the practical use and the unity of reason

Adriano Perin

2010-12-01

Full Text Available http://dx.doi.org/10.5007/1677-2954.2008v7n2p137This paper systematically discusses Kant´s argumentation in the Canon of the Critique of pure reason on the matter of the establishment of the practical use and its outcomes for the problem of the unity of reason. Bearing in mind that there is much disagreement in the literature, not only as to the specificity and function of the chapter of the Canon wi thin the various moments of Kant´s philosophy, but also as to its critical importance, the approach centers essentially on Kant´s own argumentation. The aim of this paper is to show that the Canon anticipates an important thesis of the Critique of Practical Reason, i.e., the self-sufficient legitimation of the practical use of reason in relation to its theoretical use, Moreover, is demonstrated that there are important systenatic differences between Kant´s argumentation in the Canon and in the second Critique, which lead to the uniqueness of the treatment of the problem of the unity of reason in the former text. The first part of the paper briefly presents Kant´s position in the pre-critical period on the legitimation of the practical use of reason. Thereafter, it is sustained that Kant´s search in the Canon for a "source of positive cognition" is particularly connected with his critical thesis of a self-sufficient establishment in the Canon. It is argued that, notwithstanding the anticipation of the refered critical thesis, the establishment of the practical use of reason in the Canon requires a theological consideration of morality. The third part of the paper deals with the problem of the unity of theorical and practical uses of reason in position on the establishment of the practical use reason. I come to the conclusion that the Canon guaranteed by means of a transition from the practical to the theoretical use of reason.

Kuhn, Victoria

2017-09-01

Simulations have become increasingly important for science and there is an increasing emphasis on the visualization of simulations within a Virtual Reality (VR) environment. Our group is exploring this capability as a visualization tool not just for those curious about science, but also for educational purposes for K-12 students. Using data collected in 3-D by a Time Projection Chamber (TPC), we are able to visualize nuclear and cosmic events. The Unity game engine was used to recreate the TPC to visualize these events and construct a VR application. The methods used to create these simulations will be presented along with an example of a simulation. I will also present on the development and testing of this program, which I carried out this past summer at MSU as part of an REU program. We used data from the S πRIT TPC, but the software can be applied to other 3-D detectors. This work is supported by the U.S. Department of Energy under Grant Nos.

The Culture of Unity and Some of the Great Challenges of Humankind Today

Directory of Open Access Journals (Sweden)

Cepedano Jesús Morán

2016-12-01

Full Text Available This text explores some of the great challenges present in the cultural landscape of today, such as globalization and its associated phenomena – (internationalisation and ultra-contemporaneousness; exasperated economism with its outcome in the scrap culture; the “piecemeal third world war”, according to Pope Francis’ effective expression, which is connected with a widespread and still poorly understood post-humanism and transhumanism; nihilism and the eclipse of religion as an institution. It considers the light that might be shed by the culture arising from the Focolare’s charism of unity, in order to address these challenges rigorously and without hasty demonizing. The overall picture is not intended to be negative but, without being naive, to offer an interpretation that is able to discern the work of the Spirit in the dramatic scenario of present times.

In 1971 Lord (Victor) Rothschild published his report for the government, The organisation and management of government R&D, and Sir Peter Medawar launched a campaign for the election of Sir Karl Popper to Fellowship of the Royal Society. We explore these two developments in the contexts of the then current views of the role and purpose of science, and their underpinning philosophy. Although the political battle was won by Rothschild, resulting in major changes to the funding and management of applied R&D, we argue that, despite this, Medawar's campaign for Popper provided an embattled science community with a philosophical basis for defending pure research and the unity of basic and applied science.

Controlling coulomb interactions in infrared stereometamaterials for unity light absorption

Science.gov (United States)

Mudachathi, Renilkumar; Moritake, Yuto; Tanaka, Takuo

2018-05-01

We investigate the influence of near field interactions between the constituent 3D split ring resonators on the absorbance and resonance frequency of a stereo metamaterial based perfect light absorber. The experimental and theoretical analyses reveal that the magnetic resonance red shifts and broadens for both the decreasing vertical and lateral separations of the constituents within the metamaterial lattice, analogous to plasmon hybridization. The strong interparticle interactions for higher density reduce the effective cross-section per resonator, which results in weak light absorption observed in both experimental and theoretical analyses. The red shift of the magnetic resonance with increasing lattice density is an indication of the dominating electric dipole interactions and we analyzed the metamaterial system in an electrostatic point of view to explain the observed resonance shift and decreasing absorption peak. From these analyses, we found that the fill factor introduces two competing factors determining the absorption efficiency such as coulomb interactions between the constituent resonators and their number density in a given array structure. We predicted unity light absorption for a fill factor of 0.17 balancing these two opposing factors and demonstrate an experimental absorbance of 99.5% at resonance with our 3D device realized using residual stress induced bending of 2D patterns.

Intrinsic gain (AV) measurements on Si quantum well (QW) n-channel metal-oxide-semiconductor (NMOS) transistors show that these devices can have |AV| > 1 in quantum transport negative transconductance (NTC) operation at room temperature. QW NMOS devices were fabricated using an industrial 45 nm technology node process incorporating ion implanted potential barriers to define a lateral QW in the conduction channel under the gate. While NTC at room temperature arising from transport through gate-controlled QW bound states has been previously established, it was unknown whether the quantum NTC mechanism could support gain magnitude exceeding unity. Bias conditions were found giving both positive and negative AV with |AV| > 1 at room temperature. This result means that QW NMOS devices could be useful in amplifier and oscillator applications.

Full Text Available For generic values of q, all the eigenvectors of the transfer matrix of the Uqsl(2-invariant open spin-1/2 XXZ chain with finite length N can be constructed using the algebraic Bethe ansatz (ABA formalism of Sklyanin. However, when q is a root of unity (q=eiπ/p with integer p≥2, the Bethe equations acquire continuous solutions, and the transfer matrix develops Jordan cells. Hence, there appear eigenvectors of two new types: eigenvectors corresponding to continuous solutions (exact complete p-strings, and generalized eigenvectors. We propose general ABA constructions for these two new types of eigenvectors. We present many explicit examples, and we construct complete sets of (generalized eigenvectors for various values of p and N.

Full Text Available Developing a virtual 3D environment by using game engine is a strategy to incorporate various multimedia data into one platform. The characteristic of game engine that is preinstalled with interactive and navigation tools allows users to explore and engage with the game objects. However, most CAD and GIS applications are not equipped with 3D tools and navigation systems intended to the user experience. In particular, 3D game engines provide standard 3D navigation tools as well as any programmable view to create engaging navigation thorough the virtual environment. By using a game engine, it is possible to create other interaction such as object manipulation, non playing character (NPC interaction with player and/or environment. We conducted analysis on previous game engines and experiment on urban design project with Unity3D game engine for visualization and interactivity. At the end, we present the advantages and limitations using game technology as visual representation tool for architecture and urban design studies.

Full Text Available The subject. The article investigates historical legal, theoretical-methodological and constitutional-legal problems of the formation and functioning of the institute of the head of state.The purpose of the study is to show how the constitutional functions of the head of state concretize his powers.The study is based on the use of methods of analysis and synthesis, historical legal, formal legal, comparative legal methods, scientific abstraction.The main scientific results. The authors summarize that the historical and legal analysis shows the key role of the head of state in the mechanism of ensuring state unity and law and order. Reality testifies the fact that the role of the President of the Russian Federation creates sufficient constitutional and legal grounds and conditions for the consolidated work of all state authorities, including law enforcement agencies, in the direction of ensuring the unity of state power and constitutional law and order. The indicated directions are in many ways identical, organically interrelated and interdependent, systematically define the main lines of activity of the head of state, contributing to the improvement of the constitutional and legal mechanism for ensuring the rule of law in general. Firstly, the Constitution of the Russian Federation contains only the basic powers of the President of the Russian Federation, which are substantially expanded by the legislator and presidential decrees. Secondly, the President has so-called “hidden”, discretionary powers that are not directly enshrined in the Constitution of the Russian Federation, implicit in it and stem from the sense of presidential functions that manifest themselves in unforeseen extraordinary circumstances. Thus, the constitutional design of a strong presidential power allows the President of the Russian Federation to ensure the unity of the executive power and the exercise of the powers of the federal government throughout the territory of

Little genetic variability in resilience among cattle exists for a range of performance traits across herds in Ireland differing in Fasciola hepatica prevalence.

It is anticipated that in the future, livestock will be exposed to a greater risk of infection from parasitic diseases. Therefore, future breeding strategies for livestock, which are generally long-term strategies for change, should target animals adaptable to environments with a high parasitic load. Covariance components were estimated in the present study for a selection of dairy and beef performance traits over herd-years differing in Fasciola hepatica load using random regression sire models. Herd-year prevalence of F. hepatica was determined by using F. hepatica-damaged liver phenotypes which were recorded in abattoirs nationally. The data analyzed consisted up to 83,821 lactation records from dairy cows for a range of milk production and fertility traits, as well as 105,054 young animals with carcass-related information obtained at slaughter. Reaction norms for individual sires were derived from the random regression coefficients. The heritability and additive genetic standard deviations for all traits analyzed remained relatively constant as herd-year F. hepatica prevalence gradient increased up to a prevalence level of 0.7; although there was a large increase in heritability and additive genetic standard deviation for milk and fertility traits in the observed F. hepatica prevalence levels >0.7, only 5% of the data existed in herd-year prevalence levels >0.7. Very little rescaling, therefore, exists across differing herd-year F. hepatica prevalence levels. Within-trait genetic correlations among the performance traits across different herd-year F. hepatica prevalence levels were less than unity for all traits. Nevertheless, within-trait genetic correlations for milk production and carcass traits were all >0.8 for F. hepatica prevalence levels between 0.2 and 0.8. The lowest estimate of within-trait genetic correlations for the different fertility traits ranged from -0.03 (SE = 1.09) in age of first calving to 0.54 (SE = 0.22) for calving to first service

Utilising E-on Vue and Unity 3D scenes to generate synthetic images and videos for visible signature analysis

Madden, Christopher S.; Richards, Noel J.; Culpepper, Joanne B.

2016-10-01

This paper investigates the ability to develop synthetic scenes in an image generation tool, E-on Vue, and a gaming engine, Unity 3D, which can be used to generate synthetic imagery of target objects across a variety of conditions in land environments. Developments within these tools and gaming engines have allowed the computer gaming industry to dramatically enhance the realism of the games they develop; however they utilise short cuts to ensure that the games run smoothly in real-time to create an immersive effect. Whilst these short cuts may have an impact upon the realism of the synthetic imagery, they do promise a much more time efficient method of developing imagery of different environmental conditions and to investigate the dynamic aspect of military operations that is currently not evaluated in signature analysis. The results presented investigate how some of the common image metrics used in target acquisition modelling, namely the Δμ1, Δμ2, Δμ3, RSS, and Doyle metrics, perform on the synthetic scenes generated by E-on Vue and Unity 3D compared to real imagery of similar scenes. An exploration of the time required to develop the various aspects of the scene to enhance its realism are included, along with an overview of the difficulties associated with trying to recreate specific locations as a virtual scene. This work is an important start towards utilising virtual worlds for visible signature evaluation, and evaluating how equivalent synthetic imagery is to real photographs.

3D City modelling is increasingly popular and becoming valuable tools in managing big cities. Urban and energy planning, landscape, noise-sewage modelling, underground mapping and navigation are among the applications/fields which really depend on 3D modelling for their effectiveness operations. Several research areas and implementation projects had been carried out to provide the most reliable 3D data format for sharing and functionalities as well as visualization platform and analysis. For instance, BIMTAS company has recently completed a project to estimate potential solar energy on 3D buildings for the whole Istanbul and now focussing on 3D utility underground mapping for a pilot case study. The research and implementation standard on 3D City Model domain (3D data sharing and visualization schema) is based on CityGML schema version 2.0. However, there are some limitations and issues in implementation phase for large dataset. Most of the limitations were due to the visualization, database integration and analysis platform (Unity3D game engine) as highlighted in this paper.

The amazing unity of the Universe and its origin in the Big Bang

CERN Document Server

van den Heuvel, Edward

2016-01-01

In the first chapters the author describes how our knowledge of the position of Earth in space and time has developed, thanks to the work of many generations of astronomers and physicists. He discusses how our position in the Galaxy was discovered, and how in 1929, Hubble uncovered the fact that the Universe is expanding, leading to the picture of the Big Bang. He then explains how astronomers have found that the laws of physics that were discovered here on Earth and in the Solar System (the laws of mechanics, gravity, atomic physics, electromagnetism, etc.) are valid throughout the Universe. This is illustrated by the fact that all matter in the Universe consists of atoms of the same chemical elements that we know on Earth. This unity is all the more surprising when one realizes that in the original Big Bang theory, different parts of the Universe could never have communicated with each other. It then is a mystery how they could have shared the same physical laws. This problem was solved by the introduction ...

In this paper, we proposed and realized 3D photonic nanostructures consisting of ultra-thin graded index antireflective coatings (ARCs) and woodpile photonic crystals. The use of the integrated ARC and photonic crystal structure can achieve broadband, broad-angle near unity solar absorption. The amorphous silicon based photonic nanostructure experimentally shows an average absorption of ∼95% for λ = 400–620 nm over a wide angular acceptance of θ = 0°–60°. Theoretical studies show that a Gallium Arsenide (GaAs) based structure can achieve an average absorption of >95% for λ = 400–870 nm. Furthermore, the use of the slanted SiO{sub 2} nanorod ARC surface layer by glancing angle deposition exhibits Cassie-Baxter state wetting, and superhydrophobic surface is obtained with highest water contact angle θ{sub CB} ∼ 153°. These properties are fundamentally important for achieving maximum solar absorption and surface self-cleaning in thin film solar cell applications.

Broadband unity absorption in graphene-insulator-metal (GIM) structures is demonstrated in the visible (VIS) and near-infrared (NIR) spectra. The spectral characteristics possess broadband absorption peaks, by simply choosing a stack of GIM, while no nanofabrication steps and patterning are required, and thus can be easily fabricated to cover a large area. The electromagnetic (EM) waves can be entirely trapped and the absorption can be greatly enhanced are verified with the finite-difference time-domain (FDTD) and rigorous coupled wave analysis (RCWA) methods. The position and the number of the absorption peak can be totally controlled by adjusting the thickness of the insulator layer. The proposed absorber maintains high absorption (above 90%) for both transverse electric (TE) and transverse magnetic (TM) polarizations, and for angles of incidence up to 80°. This work opens up a promising approach to realize perfect absorption (PA) with ultra-thin film, which could implicate many potential applications in optical detection and optoelectronic devices.

Creation of Unit Theory Oil Generation based on a number of the provisions, one of which is the unity of the hydrocarbon composition in various geological objects. Studies conducted in various geological conditions and tectonic - magmatic environment. In studying the hydrocarbon composition of various geological objects, untraditional for petroleum geology (igneous rocks, metamorphic rocks, mineral deposits, etc.) progressively manifested that hydrocarbons are also distributed and have the following features. Studies have shown: 1. The composition of the hydrocarbon components presented by, light hydrocarbons, heavy hydrocarbons up to including hexane, normal forms, isoforms, saturated and unsaturated hydrocarbons. 2. Hydrocarbon composition and the ratio of methane to heavy hydrocarbons corresponds to the composition of gases gas fields. 3. The composition and the ratio of hydrocarbons do not depend on genetic types of heterogeneous geological objects. 4. Gas saturation meets the prevailing structure of rocks - pores or fractures. The foregoing allows us to speak of a single source of generating and delivering hydrocarbons in the Earth's Crust, regardless of the geological situation. I.e. the presence of hydrocarbons in the Earth's Crust is UNITED! 5. From a practical point of view - virtually unconventional for hydrocarbons rock can serve as unconventional hydrocarbon resources.

Zames (1981) has observed that there is, in general, no 'separation principle' to guarantee optimality of a division between control law design and filtering of plant uncertainty. Peczkowski and Sain (1978) have solved a model matching problem using transfer functions. Taking into consideration this investigation, Peczkowski et al. (1979) proposed the Total Synthesis Problem (TSP), wherein both the command/output-response and command/control-response are to be synthesized, subject to the plant constraint. The TSP concept can be subdivided into a Nominal Design Problem (NDP), which is not dependent upon specific controller structures, and a Feedback Synthesis Problem (FSP), which is. Gejji (1980) found that NDP was characterized in terms of the plant structural matrices and a single, 'good' transfer function matrix. Sain et al. (1981) have extended this NDP work. The present investigation is concerned with a study of FSP for the unity feedback case. NDP, together with feedback synthesis, is understood as a Total Synthesis Problem.

Nonfullerene solar cells have increased their efficiencies up to 13%, yet quantum efficiencies are still limited to 80%. Here we report efficient nonfullerene solar cells with quantum efficiencies approaching unity. This is achieved with overlapping absorption bands of donor and acceptor that increases the photon absorption strength in the range from about 570 to 700 nm, thus, almost all incident photons are absorbed in the active layer. The charges generated are found to dissociate with negligible geminate recombination losses resulting in a short-circuit current density of 20 mA cm -2 along with open-circuit voltages >1 V, which is remarkable for a 1.6 eV bandgap system. Most importantly, the unique nano-morphology of the donor:acceptor blend results in a substantially improved stability under illumination. Understanding the efficient charge separation in nonfullerene acceptors can pave the way to robust and recombination-free organic solar cells.

Full Text Available The work of the humanist Pedro de Valencia belongs to “biblical humanism”. Religion and politics are inseparable in the work of this author. In the sixteenth century, a part of the population in Spain still subscribed to Jewish or Islamic thought. The Spanish church was making a huge effort at the time to integrate within the traditional Catholicism converts from these two communities. In this conflict the justifications of religious identity in various writings of Pedro de Valencia can be located. The common denominator of the writings discussed is summarized in the idea of religious unity of Conversos and Moriscos under the authority of the king in response to the conflicts in the Spain of the time.La obra del humanista Pedro de Valencia pertenece al «humanismo biblista».

2014-12-01

The main objectives of the paper are to (1) present an overview of nonlocal integral elasticity and Aifantis gradient elasticity theory and (2) discuss the application of partition of unity methods to study the response of low-dimensional structures. We present different choices of approximation functions for gradient elasticity, namely Lagrange intepolants, moving least-squares approximants and non-uniform rational B-splines. Next, we employ these approximation functions to study the response of nanobeams based on Euler-Bernoulli and Timoshenko theories as well as to study nanoplates based on first-order shear deformation theory. The response of nanobeams and nanoplates is studied using Eringen's nonlocal elasticity theory. The influence of the nonlocal parameter, the beam and the plate aspect ratio and the boundary conditions on the global response is numerically studied. The influence of a crack on the axial vibration and buckling characteristics of nanobeams is also numerically studied.

The Molla Sadra believes that the Principle of causality with its branches constitutes a single body, and its acceptance is considered as postulate. Discussion about the criteria of neediness of effect to cause is considered branch of the general law of causality which is necessary in discussion of causal necessity. It is obvious that Molla Sadra 's view in determining the criteria for the neediness is the Possibility in the sense of need. as regards, this principle is itself a branch of the general principle of causality, and the Islamic philosophers think if someone refuses to accept a branch of causality, cannot believe in a causal system in the world. and as regards, the principle of cognation Is assumed to be identical with the intellectual rule of Al-vaheed(from The one will not be issued except the one and the principle of The impossibility of infinite regress are other important branches of the principle of causality; acceptance of this branches Required in duality in the outside world from mind and dividing existence to the cause and effect and grades in the reality of existence.

Full Text Available Jalal al-Din Rumi and Muhammad Hafez Shirazi are two of the great mystics, Sufis, writing in Persian in the 13th and 14th century. Their poetry is still an essential part of the Turkish and the Persian religious and cultural settings. The objectives of this article are to suggest a method for analyzing the poetry of Rumi and Hafez within the discipline of History of religions. The various combinations of symbols, symbolic clusters, together create a totality from which parts are taken and combined in various ways in the poems. Seldom all of them are there together, but reading some poems with various themes gives the whole combination of symbols, which has been used by the poet. It gives the picture of a Sufi setting, where the essential thing is the path to the unity with God. With it goes the Persian identity indicated in the garden of roses symbolizing paradise, kingship, justice, prosperity, the love of nature etc. Only in combination do these symbols point to the complex situation of the Persian Sufis.

THE SPECIFICITY OF FREEDOM AND CREATIVITY ETHICS IN N. BERDYAEV’S PHILOSOPHY OF EDUCATION

2013-04-01

Full Text Available The specificity of N. Berdyaev’s freedom and creativity ethics reflects its implicit pedagogical potential, consisting in original religious and philosophical treatment of education. The source of education is the image of God in man, the way of education is a free communion with the truth, the sense of education is restoring God’s image of man through free creative response to God’s call. N. Berdyaev marks out a special educational role of Christianity in the world history, which is seen as a global educational process of spiritual and moral education of the whole mankind. The ethical and pedagogical teaching of N. Berdyaev is not teleological, but a spiritual and energetical one. In fact, it denies single-sided dominance of ends over means, considers them to be the inseparable unity in order to avoid ideal objectification. In this respect, the way of education is not less important than its ends, and education itself appears to be not the means of living but the sense, contents and way of “the life of spirit”.

Pure state consciousness and its local reduction to neuronal space

Science.gov (United States)

Duggins, A. J.

2013-01-01

The single neuronal state can be represented as a vector in a complex space, spanned by an orthonormal basis of integer spike counts. In this model a scalar element of experience is associated with the instantaneous firing rate of a single sensory neuron over repeated stimulus presentations. Here the model is extended to composite neural systems that are tensor products of single neuronal vector spaces. Depiction of the mental state as a vector on this tensor product space is intended to capture the unity of consciousness. The density operator is introduced as its local reduction to the single neuron level, from which the firing rate can again be derived as the objective correlate of a subjective element. However, the relational structure of perceptual experience only emerges when the non-local mental state is considered. A metric of phenomenal proximity between neuronal elements of experience is proposed, based on the cross-correlation function of neurophysiology, but constrained by the association of theoretical extremes of correlation/anticorrelation in inseparable 2-neuron states with identical and opponent elements respectively.

Diagonal Eigenvalue Unity (DEU) code for spectral amplitude coding-optical code division multiple access

Science.gov (United States)

Ahmed, Hassan Yousif; Nisar, K. S.

2013-08-01

Code with ideal in-phase cross correlation (CC) and practical code length to support high number of users are required in spectral amplitude coding-optical code division multiple access (SAC-OCDMA) systems. SAC systems are getting more attractive in the field of OCDMA because of its ability to eliminate the influence of multiple access interference (MAI) and also suppress the effect of phase induced intensity noise (PIIN). In this paper, we have proposed new Diagonal Eigenvalue Unity (DEU) code families with ideal in-phase CC based on Jordan block matrix with simple algebraic ways. Four sets of DEU code families based on the code weight W and number of users N for the combination (even, even), (even, odd), (odd, odd) and (odd, even) are constructed. This combination gives DEU code more flexibility in selection of code weight and number of users. These features made this code a compelling candidate for future optical communication systems. Numerical results show that the proposed DEU system outperforms reported codes. In addition, simulation results taken from a commercial optical systems simulator, Virtual Photonic Instrument (VPI™) shown that, using point to multipoint transmission in passive optical network (PON), DEU has better performance and could support long span with high data rate.

F response and H reflex analysis of physiological unity of gravity and antigravity muscles in man.

Science.gov (United States)

García, H A; Fisher, M A

1977-01-01

Observational differences between reflex (H reflex) and antidromic (F response) activation of segmental motoneurons by a peripheral electrical stimulus are described. In contrast to H reflexes, the percentage of F responses found after a series of stimuli is directly related to the pick-up field of the recording electrode consistent with this response being due to the variable activation of a small fraction of the available motoneuron pool. Despite the differing physiological mechanisms, both F responses and H reflexes can be used to demonstrate similar relative "central excitatory states" for antigravity muscles (i.e. extensors in the lower extremity and flexors in the upper extremity) and their antagonist gravity muscles. H reflexes were elicited not only in their usual location in certain antigravity muscles but also in unusual locations by length/tension changes in agonist and antagonist groups as well as by passive stretch. The data argue for the physiological unity of similarly acting gravity and antigravity muscles as well as supporting a meaningful role of group II afferents in normal segmental motoneuron pool excitability.

Near-unity transparency of a continuous metal film via cooperative effects of double plasmonic arrays

2013-01-01

Metal structures with high optical transparency and conductivity are of great importance for practical applications in optoelectronic devices. Here we investigate the transparency response of a continuous metal film sandwiched by double plasmonic nanoparticle arrays. The upper nanoparticle array shows efficient light trapping of the incident field, acting as a light input coupler, and the lower nanoparticle array shows a light release gate opening at the other side, acting as the light output coupler. The strong near-field light–matter interactions of the nano-scale separated plasmonic nanoparticles, the excitation of surface plasmon waves of the metal film, and their cooperative coupling effects result in broadband scattering cancellation and near-unity transparency (up to 96%) in the optical regime. The transparency response in such a structure can be efficiently modified by varying the gap distance of adjacent nanoparticles, dielectric environments, and the distance between the plasmonic array and the metal film. This motif may provide a new alternative approach to obtain transparent and highly conducting metal structures with potential applications in transparent conductors, plasmonic filters, and highly integrated light input and output components.

When the input-output mapping of a one-layered perceptron (OLP) does NOT meet the PLI condition which is the if-and- only-if, or 'IFF, condition that the mapping can be realized by a OLP, then no matter what learning rule we use, a OLP just cannot realize this mapping at all. However, because of the nature of the PLI, one can still construct a parallel- cascaded, two-layered perceptron system to realize this `illegal' mapping. Theory and design example of this novel design will be reported in detail in this paper.

Bidentate Ligand-passivated CsPbI3 Perovskite Nanocrystals for Stable Near-unity Photoluminescence Quantum Yield and Efficient Red Light-emitting Diodes

Pan, Jun

2017-12-17

Although halide perovskite nanocrystals (NCs) are promising materials for optoelectronic devices, they suffer severely from chemical and phase instabilities. Moreover, the common capping ligands like oleic acid and oleylamine that encapsulate the NCs will form an insulating layer, precluding their utility in optoelectronic devices. To overcome these limitations, we develop a post-synthesis passivation process for CsPbI3 NCs by using a bidentate ligand, namely 2,2’-Iminodibenzoic acid. Our passivated NCs exhibit narrow red photoluminescence with exceptional quantum yield (close to unity) and substantially improved stability. The passivated NCs enabled us to realize red light-emitting diodes (LEDs) with 5.02% external quantum efficiency and 748 cd/m2 luminance, surpassing by far LEDs made from the non-passivated NCs.

Moreover, the common capping ligands like oleic acid and oleylamine that encapsulate the NCs will form an insulating layer, precluding their utility in optoelectronic devices. To overcome these limitations, we develop a post-synthesis passivation process for CsPbI3 NCs by using a bidentate ligand, namely 2,2’-Iminodibenzoic acid. Our passivated NCs exhibit narrow red photoluminescence with exceptional quantum yield (close to unity) and substantially improved stability. The passivated NCs enabled us to realize red light-emitting diodes (LEDs) with 5.02% external quantum efficiency and 748 cd/m2 luminance, surpassing by far LEDs made from the non-passivated NCs.

Full Text Available The Volta Grande Environmental Unity represents one of the few remnants of Cerrado protected by areserve in the Triângulo Mineiro region, municipalities of Conceição das Alagoas (19°55' S, 48°23' W andMiguelópolis (20°12' S, 48°03' W, in the states of Minas Gerais and São Paulo, respectively. The mammalian fauna ofthis reserve was inventoried between 2003 and 2004 to generate estimates about taxonomic composition, richness, andabundance of species. A sampling effort of 832 trapping-nights resulted in 24 species recorded. Cumulative curvessuggest that the overall inventory is not complete and that more species are likely to be registered. The majority ofspecies recorded is widespread along the Cerrado, but include some noteworthy records of endangered species, such asthe Giant anteater (Myrmecophaga tridactyla and the Manned wolf (Chrysocyon brachyurus. The record of thearboreal cricetid rodent Oecomys bicolor represents a slight extension of the southeastern limit of its distribution.

Full Text Available The specificity of N. Berdyaev’s freedom and creativity ethics reflects its implicit pedagogical potential, consisting in original religious and philosophical treatment of education. The source of education is the image of God in man, the way of education is a free communion with the truth, the sense of education is restoring God’s image of man through free creative response to God’s call. N. Berdyaev marks out a special educational role of Christianity in the world history, which is seen as a global educational process of spiritual and moral education of the whole mankind. The ethical and pedagogical teaching of N. Berdyaev is not teleological, but a spiritual and energetical one. In fact, it denies single-sided dominance of ends over means, considers them to be the inseparable unity in order to avoid ideal objectification. In this respect, the way of education is not less important than its ends, and education itself appears to be not the means of living but the sense, contents and way of “the life of spirit”.DOI: http://dx.doi.org/10.12731/2218-7405-2013-4-12

Full Text Available In light of the fact that Far-eastern martial arts have to be viewed as an inseparable part of the cultural traditions of China and Japan, their aesthetic character is tied to traditional cultural concepts which dominate these cultures, such as the concept of the unity of opposites, better known as yin and yang; the concept of the Road (the Tao as a symbol of continuing self-improvement; the concept of Chi or Qui energy which permeates the cosmos as well as individual beings, etc. These concepts owe their existence and development first and foremost to the religious and philosophical systems which shaped and influenced all segments of these two great cultures, and not just the martial tradition. On the other hand, performance arts weren’t spared this same influence. Performance arts and martial arts of the Far East had an intertwined history and strongly influenced each other. The aim of this paper will be to give an outline of the basic concepts connected to the aesthetics of the martial arts of China and Japan and point out the similar roots in other segments of cultural tradition.

Electronic portal imaging devices (EPIDs) are frequently used in external beam radiation therapy for dose verification purposes. The aim of this study was to investigate the dose-response characteristics of the EPID in the Unity MR-linac (Elekta AB, Stockholm, Sweden) relevant for dosimetric applications under clinical conditions. EPID images and ionization chamber (IC) measurements were used to study the effects of the magnetic field, the scatter generated in the MR housing reaching the EPID, and inhomogeneous attenuation from the MR housing. Dose linearity and dose rate dependencies were also determined. The magnetic field strength at EPID level did not exceed 10 mT, and dose linearity and dose rate dependencies proved to be comparable to that on a conventional linac. Profiles of fields, delivered with and without the magnetic field, were indistinguishable. The EPID center had an offset of 5.6 cm in the longitudinal direction, compared to the beam central axis, meaning that large fields in this direction will partially fall outside the detector area and not be suitable for verification. Beam attenuation by the MRI scanner and the table is gantry angle dependent, presenting a minimum attenuation of 67% relative to the 90° measurement. Repeatability, observed over two months, was within 0.5% (1 SD). In order to use the EPID for dosimetric applications in the MR-linac, challenges related to the EPID position, scatter from the MR housing, and the inhomogeneous, gantry angle-dependent attenuation of the beam will need to be solved.

A recent proof of Bell's theorem without inequalities [A. Cabello, Phys.Rev.Lett. 86, 1911 (2001)] is formulated as a Greenberger-Horne-Zeilinger--type proof involving just two observers. On one hand, this new approach allows us to derive an experimentally testable Bell inequality which is violated by quantum mechanics. On the other hand, it leads to a new state-independent proof of the Kochen-Specker theorem and provides a wider perspective on the relations between the major proofs of no hidden variables

Superconductivity and fusion energy—the inseparable companions

Science.gov (United States)

Bruzzone, Pierluigi

2015-02-01

Although superconductivity will never produce energy by itself, it plays an important role in energy-related applications both because of its saving potential (e.g., power transmission lines and generators), and its role as an enabling technology (e.g., for nuclear fusion energy). The superconducting magnet’s need for plasma confinement has been recognized since the early development of fusion devices. As long as the research and development of plasma burning was carried out on pulsed devices, the technology of superconducting fusion magnets was aimed at demonstrations of feasibility. In the latest generation of plasma devices, which are larger and have longer confinement times, the superconducting coils are a key enabling technology. The cost of a superconducting magnet system is a major portion of the overall cost of a fusion plant and deserves significant attention in the long-term planning of electricity supply; only cheap superconducting magnets will help fusion get to the energy market. In this paper, the technology challenges and design approaches for fusion magnets are briefly reviewed for past, present, and future projects, from the early superconducting tokamaks in the 1970s, to the current ITER (International Thermonuclear Experimental Reactor) and W7-X projects and future DEMO (Demonstration Reactor) projects. The associated cryogenic technology is also reviewed: 4.2 K helium baths, superfluid baths, forced-flow supercritical helium, and helium-free designs. Open issues and risk mitigation are discussed in terms of reliability, technology, and cost.

Geomicrobiology; inseparable from low temperature geochemistry & mineralogy

Science.gov (United States)

Southam, G.

2009-05-01

Bacteria play an important role in catalyzing a wide array of biogeochemical processes that affect the dissolution of minerals, the aqueous geochemistry of their surroundings and secondary mineral formation. Processes occurring at the bacteria-mineral interface can occur on the scale of nanoenvironments and will normally extend to microenvironments or even, to macroscopic features where extensive growth of bacteria is supported. The action of bacteria in these systems can produce a wide range of biomarkers that can be preserved over geologic time periods. Possible biomarkers include dissolution features in mineral substrates, fossil structures of individual cells to complex cell-cell associations, and chemical (isotopic and organic) signatures. In any system, we need to focus at the scale of the bacteria themselves to appreciate the actual chemistry of their surroundings and the kinds of reactions that they can catalyse. For example, photosynthetic microbial mats in an Atlin, BC wetland create ideal conditions for biologically induced precipitation of magnesium carbonates, specifically dypingite Mg5(CO3)4(OH)25H2O, which we were unable to reproduce abiotically. The preservation of biosignatures over geologic time presents obvious challenges, and the effect of diagenesis on fossils and their mineralogical assemblages deserves attention, especially with respect to the preservation and analysis of materials on (or from) Mars. For this, we need to rely on our Earth analogue sites as a way to triage the wide range of samples that are available for collection and analysis. The preservation of organic materials and cells in salts is particularly interesting. Conversely, the hematite nodules on Mars may not be good samples to target in the search for a Martian biosphere. The possibility of finding an extant biosphere increases with depth; however, evidence from Earth's deep subsurface demonstrates that it does not contain an abundant biosphere. Bacteria thrive in geochemical gradients where they take advantage of disequilibrium conditions to generate the energy needed to fight entropy. The selection of analogue sites needs to focus on the habitable conditions and preservation potential of these sites in order to increase our chances of finding evidence of life, to better understand how it is preserved on Earth, and by extension, to determine where it might be preserved on Mars.

Prevalence of stuttering.

The prevalence of stuttering in a university population was 2.1%; 3.4% were former stutterers. More men than women stuttered. Right handed female stutterers were less likely to have "lost" their stutter than were right handed males. Stutterers, past stutterers, and questionable stutterers all had a family history of stuttering. The significant prevalence of stuttering, the increased prevalence among males, the lack of a decline of this disorder over the past few decades despite the increased number of speech clinicians and data concerning handedness, emphasise the need to investigate organic causes of stuttering.

Worldview, the credit crisis and the ‘unity of life’. From ‘framework’ to ‘deep commitment’

2012-10-01

Full Text Available The term ‘worldview’ harbours different dimensions that are not always clearly distinguished. A worldview can be considered to be a personal matter, but it may also be a more collective phenomenon, as it can manifest itself for example within a certain sphere of life (e.g. politics or economics as a full-blown ideology or a more implicit ‘embedded worldview’. A second distinction can be made between the dimension of a deep, existential commitment and that of an encompassing mental framework, between spiritual inspiration and a more or less intellectually coherent system. There may be tensions between these various dimensions. Having a worldview as a person may imply being in conflict with other worldviews that are embodied in certain social fields. How can people deal with these conflicts? One can easily be seduced to avoid the conflicts and to shift gears between them. With the credit crisis and economics used as an illustration, this article explores some of the techniques that people – consciously, semi-consciously or unconsciously – may employ to navigate the differences between various social domains and their inherent worldviews. In order to support people to regain some unity, the notion of worldview may still be helpful, but interpreted primarily as ‘deep commitment’.

The diversity and unity of reactor noise theory

International Nuclear Information System (INIS)

Kuang, Zhifeng

2001-01-01

The study of reactor noise theory concerns questions about cause and effect relationships, and the utilisation of random noise in nuclear reactor systems. The diversity of reactor noise theory arises from the variety of noise sources, the various mathematical treatments applied and the various practical purposes. The neutron noise in zero-energy systems arises from the fluctuations in the number of neutrons per fission, the time between nuclear events, and the type of reactions. It can be used to evaluate system parameters. The mathematical treatment is based on the master equation of stochastic branching processes. The noise in power reactor systems is given rise by random processes of technological origin such as vibration of mechanical parts, boiling of the coolant, fluctuations of temperature and pressure. It can be used to monitor the reactor behaviour with the possibility of detecting malfunctions at an early stage. The mathematical treatment is based on the Langevin equation. The unity of reactor noise theory arises from the fact that the useful information from noise is embedded in the second moments of random variables, which lends the possibility of building up a unified mathematical description and analysis of the various reactor noise sources. Exploring such possibilities is the main subject among the three major topics reported in this thesis. The first subject is within the zero power noise in steady media, and we reported on the extension of the existing theory to more general cases. In Paper I, by use of the master equation approach, we have derived the most general Feynman- and Rossi-alpha formulae so far by taking the full joint statistics of the prompt and all the six groups of delayed neutron precursors, and a multiple emission source into account. The involved problems are solved with a combination of effective analytical techniques and symbolic algebra codes. Paper II gives a numerical evaluation of these formulae. An assessment of the

Musical Genre as an Indicator of the Unity in Diversity Concept: Case Study of the ESC’S Winning Song Hard Rock Hallelujah

Full Text Available In this paper, the author questions the role of musical genre presented on the Eurovision Song Contest in the context of the unity in diversity concept, recognized as one of the markers of European cultural identity. Interpretation of this concept in sociological theory is presented while arguing that it could be understood in the history of the contest. A broader view on genres presented in the first decades of the contest is offered, before focusing on a case study of Finland’s 2006 winning song. Although unusual in a purely musical sense in the context of the ESC, it is argued that this entry is more understandable when more determinants of performing European identity on the ESC stage are included in the interpretation, and that music serves as only one of those determinants and thus should be interpreted as cultural discoursive practice.

Full Text Available African healing tradition is holistic by nature, involving an essential unity between the spiritual, psycho-somatic and social dimension of health. All these dimensions constitute an inseparable part of the total therapeutic system. The traditional conception of health and illness in Africa is connected to a wider framework of religion and social reality. Illness is thus not seen as a mere disruption of physical and psychological integrity of an individual, but as an affliction caused by the intervention of different invisible powers such as spirits, demons, ghosts and witches that are believed to penetrate the whole of life. Diagnostic, therapeutic and prophylactic activity of the traditional healers – ngangas (how they are called in many Bantu languages as well as prophets of African independent churches, namely those of Pentecostal and charismatic type, are based on a common culturally shared aetiology such as natural diseases, spirit possession and witchcraft. Indigenous African healing was historically shaped by process of colonialism during which the traditional medicine was rather persecuted, on the contrary the epoch of post-colonialism brought its revalorization, its recognition by most of the African national government. The traditional medicine of many African states today is thus represented as a  constitutive part of national cultural heritage.

Enhancing body awareness has been described as a key element or a mechanism of action for therapeutic approaches often categorized as mind-body approaches, such as yoga, TaiChi, Body-Oriented Psychotherapy, Body Awareness Therapy, mindfulness based therapies/meditation, Feldenkrais, Alexander Method, Breath Therapy and others with reported benefits for a variety of health conditions. To better understand the conceptualization of body awareness in mind-body therapies, leading practitioners and teaching faculty of these approaches were invited as well as their patients to participate in focus groups. The qualitative analysis of these focus groups with representative practitioners of body awareness practices, and the perspectives of their patients, elucidated the common ground of their understanding of body awareness. For them body awareness is an inseparable aspect of embodied self awareness realized in action and interaction with the environment and world. It is the awareness of embodiment as an innate tendency of our organism for emergent self-organization and wholeness. The process that patients undergo in these therapies was seen as a progression towards greater unity between body and self, very similar to the conceptualization of embodiment as dialectic of body and self described by some philosophers as being experienced in distinct developmental levels.

Patton, T.

2015-01-01

This project centres on the development of a virtual nuclear facility environment to assist non-proliferation and nuclear arms control practitioners - including researchers, negotiators, or inspectors - in developing and refining a verification system and secure chain of custody of material or equipment. The platform for creating the virtual facility environment is the Unity 3D game engine. This advanced platform offers both the robust capability and flexibility necessary to support the design goals of the facility. The project also employs Trimble SketchUp and Blender 3D for constructing the model components. The development goal of this phase of the project was to generate a virtual environment that includes basic physics in which avatars can interact with their environment through actions such as picking up objects, operating vehicles, dismantling a warhead through a spherical representation system, opening/closing doors through a custom security access system, and conducting CCTV surveillance. Initial testing of virtual radiation simulation techniques was also explored in preparation for the next phase of development. Some of the eventual utilities and applications for this platform include: 1. conducting live multi-person exercises of verification activities within a single, shared virtual environment, 2. refining procedures, individual roles, and equipment placement in the contexts of non-proliferation or arms control negotiations 3. hands on training for inspectors, and 4. a portable tool/reference for inspectors to use while carrying out inspections. This project was developed under the Multilateral Verification Project, led by the Verification Research, Training and Information Centre (VERTIC) in the United Kingdom, and financed by the Norwegian Ministry of Foreign Affairs. The environment was constructed at the Vienna Center for Disarmament and Non-Proliferation (VCDNP). (author)

But on the other hand, Molla Sadra talks about personal unity of existence and also considers it as the conclusion of his intellectual analysis, not as something merely mystical and has explicit expressions such as :   «Ù„یس لما سوی الواحد الحق وØ‌ود لا استقلالی ولا تعلقی بل وØ‌وداتها لیس الا تطورات الحق باطواره و شئوناته بشئونه الذاتیه»   In views of Professor Motahari and Professor Javadi Amoli which both are raised in Sadraism system , and the originality of existence and

How prevalent is 'food addiction'?

Directory of Open Access Journals (Sweden)

Adrian eMeule

2011-11-01

Full Text Available Increasing evidence suggests that binge eating-related disorders could be related to addiction-like eating patterns due to the addictive potential of hyperpalatable foods. Subsequently, important implications have been derived for treatment of those disorders and even political actions. However, studies on the prevalence of food addiction are rare. Few recent studies investigated addictive eating in children, adolescents, and adults. This mini-review presents these first attempts to assess addictive eating and how prevalent addictive eating patterns were in the respective studies. It is concluded that the prevalence of food addiction is increased in obese individuals and even more so in obese patients with binge eating disorder. However, prevalence of food addiction is not sufficient to account for the obesity epidemic. Conversely, an arguably high prevalence of food addiction can also be found in under-, normal-, and overweight individuals. Future studies may investigate which factors are associated with addictive eating in non-obese individuals.

The prevalence estimates vary with a factor 100. As the results vary so do the study populations. 6 If the different study populations are accounted for, a common conclusion can be drawn: Food additive intolerance is found in adults with atopic symptoms from the respiratory tract and skin. The prevalence......1 The existing prevalence estimates of food additive intolerance(1-4) are being reviewed. 2 In the EEC report the estimated frequency of food additive intolerance is 0.03% to 0.15% based on data from patient groups. 3 The British population study results in a prevalence estimate of 0.......026%. The challenged population is 81 children and adults with a history of reproducible clinical symptoms after ingestion of food additives. 4 In the Danish population study a prevalence of 1-2% is found in children age 5-16. In this study a total of 606 children mainly with atopic disease have been challenged. 5...

Analysis of self-reported versus biomarker based smoking prevalence: methodology to compute corrected smoking prevalence rates.

Prevalence of smoking is needed to estimate the need for future public health resources. To compute and compare smoking prevalence rates by using self-reported smoking statuses, two serum cotinine (SCOT) based biomarker methods, and one urinary 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) based biomarker method. These estimates were then used to develop correction factors to be applicable to self-reported prevalences to arrive at corrected smoking prevalence rates. Data from National Health and Nutrition Examination Survey (NHANES) for 2007-2012 for those aged ≥20 years (N = 16826) were used. Self-reported prevalence rate for the total population computed as the weighted number of self-reported smokers divided by weighted number of all participants was 21.6% and 24% when computed by weighted number of self-reported smokers divided by the weighted number of self-reported smokers and nonsmokers. The corrected prevalence rate was found to be 25.8%. A 1% underestimate in smoking prevalence is equivalent to not being able to identify 2.2 million smokers in US in a given year. This underestimation, if not corrected, could lead to serious gap in the public health services available and needed to provide adequate preventive and corrective treatment to smokers.

Speed and automaticity of word recognition - inseparable twins?

Poulsen, Mads; Asmussen, Vibeke; Elbro, Carsten

'Speed and automaticity' of word recognition is a standard collocation. However, it is not clear whether speed and automaticity (i.e., effortlessness) make independent contributions to reading comprehension. In theory, both speed and automaticity may save cognitive resources for comprehension...... processes. Hence, the aim of the present study was to assess the unique contributions of word recognition speed and automaticity to reading comprehension while controlling for decoding speed and accuracy. Method: 139 Grade 5 students completed tests of reading comprehension and computer-based tests of speed...... of decoding and word recognition together with a test of effortlessness (automaticity) of word recognition. Effortlessness was measured in a dual task in which participants were presented with a word enclosed in an unrelated figure. The task was to read the word and decide whether the figure was a triangle...

The coastal population of British Columbia is projected to increase by a million people over the next 20 years. Population growth in the region will increase pressure on the environment through land-use changes and water demand, and the discharge of wastes and pollutants. Changes to the environment will have an impact on industries such as forestry, fishing, and tourism that depend on healthy ecosystems. Six technical papers were presented in this volume as part of a project reporting on the coastal environment of British Columbia. The volume was compiled to help in the future-decision making processes in the province. Reporting for the project focused on a region extending westward from the height of the Coast Mountains, and included the marine area within Canada's 200-mile limit. Papers were presented on the following topics: (1) population and economic activity; (2) climate change; (3) industrial contaminants; (4) ecosystem protection; (5) bio-diversity; and (6) fisheries. Each of the 6 papers provided an overview of issues related to their topic, a set of indicators, and a summary of results. refs., tabs., figs

EuroPrevall is an EU-funded multidisciplinary project including 62 institutions from 22 countries. EuroPrevall studies the prevalence and distribution of food allergies in infants, children, adolescents, and adults in Europe, threshold doses for allergenic foods, the role of the environment in food allergy, the socioeconomic impact of food allergy, and novel diagnostic tools for food allergies. The EuroPrevall serum bank (EPASB), containing samples from approximately 70,000 subjects, is a major tool to achieve these goals. EPASB is coordinated by the Paul-Ehrlich-Institut, Langen, Germany. Local sera collections are administered at the University of Amsterdam (NL), the University Hospital of Manchester (UK), Charité Hospital (DE) and the Paul-Ehrlich-Institut. The EPASB coordinator and managing partners distribute samples for experimental work and regulate access. The overall aim is to provide sera to fulfil EuroPrevall research goals. The EPASB coordinator and managing partners suggest appropriate sera for addressing specific scientific and diagnostic questions. The serum bank will be maintained after termination of the project, but subsequent investigations must be in accordance with the original research goals of EuroPrevall. Thus, the contributors of the sera retain control over their future use. This rule prevents investigation of questions outside the scope of EuroPrevall, e.g. the allergenicity of genetically-modified foods.

One of the main ways in transmitting parasites to humans is through consuming contaminated raw vegetables. The aim of this study was to evaluate the prevalence of parasitological contamination (helminthes eggs, Giardia and Entamoeba histolytica cysts) of salad vegetables sold at supermarkets and street vendors in Amman and Baqa’a – Jordan. A total of 133 samples of salad vegetables were collected and examined for the prevalence of parasites. It was found that 29% of the samples were contaminated with different parasites. Of the 30 lettuce, 33 tomato, 42 parsley and 28 cucumber samples examined the prevalence of Ascaris spp. eggs was 43%, 15%, 21% and 4%; Toxocara spp. eggs was 30%, 0%, 0% and 4%; Giardia spp. cysts was 23%, 6%, 0% and 0%; Taenia/Echinococcus eggs was 20%, 0%, 5% and 0%; Fasciola hepatica eggs was 13%, 3%, 2% and 0%; and E. histolytica cysts was 10%, 6%, 0% and 0%, respectively. There was no significant difference in the prevalence of parasite in salad vegetables either between supermarkets and street vendors, or between Amman and Baqa’a, Ascaris spp. was found to be the highest prevalent parasite in salad vegetables from supermarkets and street vendors and from Amman and Baqa’a. Our results pointed out that, the parasitic contamination of salad vegetables found in our study might be caused by irrigating crops with faecal contaminated water. We concluded that salad vegetables sold in Amman and Baqa’a may cause a health risk to consumers.

Outer-shell s0/p0 orbital mixing with d10 orbitals and symmetry reduction upon cupriphication of cyclic trinuclear trigonal-planar gold(I) complexes are found to sensitize ground-state Cu(I)–Au(I) covalent bonds and near-unity phosphorescence quantum yields. Heterobimetallic Au4Cu2 {[Au4(μ-C2,N3-EtIm)4Cu2(µ-3,5-(CF3)2Pz)2], (4a)}, Au2Cu {[Au2(μ-C2,N3-BzIm)2Cu(µ-3,5-(CF3)2Pz)], (1) and [Au2(μ-C2,N3-MeIm)2Cu(µ-3,5-(CF3)2Pz)], (3a)}, AuCu2 {[Au(μ-C2,N3-MeIm)Cu2(µ-3,5-(CF3)2Pz)2], (3b) and [Au(μ-C2,N3-EtIm)Cu2(µ-3,5-(CF3)2Pz)2], (4b)} and stacked Au3/Cu3 {[Au(μ-C2,N3-BzIm)]3[Cu(µ-3,5-(CF3)2Pz)]3, (2)} form upon reacting Au3 {[Au(μ-C2,N3-(N-R)Im)]3 ((N-R)Im = imidazolate; R = benzyl/methyl/ethyl = BzIm/MeIm/EtIm)} with Cu3 {[Cu(μ-3,5-(CF3)2Pz)]3 (3,5-(CF3)2Pz = 3,5-bis(trifluoromethyl)pyrazolate)}. The crystal structures of 1 and 3a reveal stair-step infinite chains whereby adjacent dimer-of-trimer units are noncovalently packed via two Au(I)⋯Cu(I) metallophilic interactions, whereas 4a exhibits a hexanuclear cluster structure wherein two monomer-of-trimer units are linked by a genuine d10–d10 polar-covalent bond with ligand-unassisted Cu(I)–Au(I) distances of 2.8750(8) Å each—the shortest such an intermolecular distance ever reported between any two d10 centers so as to deem it a “metal–metal bond” vis-à-vis “metallophilic interaction.” Density-functional calculations estimate 35–43 kcal/mol binding energy, akin to typical M–M single-bond energies. Congruently, FTIR spectra of 4a show multiple far-IR bands within 65–200 cm−1, assignable to vCu-Au as validated by both the Harvey–Gray method of crystallographic-distance-to-force-constant correlation and dispersive density functional theory computations. Notably, the heterobimetallic complexes herein exhibit photophysical properties that are favorable to those for their homometallic congeners, due to threefold-to-twofold symmetry reduction, resulting in cuprophilic

The never-ending tension between finding food and avoiding predators may be the most universal natural stressor wild animals experience. The 'chronic stress' hypothesis predicts: (i) an animal's stress profile will be a simultaneous function of food and predator pressures given the aforesaid tension; and (ii) these inseparable effects on physiology will produce inseparable effects on demography because of the resulting adverse health effects. This hypothesis was originally proposed to explain...

Fourth revolution in psychiatry - Addressing comorbidity with chronic physical disorders.

Gautam, Shiv

2010-07-01

The moral treatment of mental patients, Electro Convulsive therapy (ECT), and Psychotropic medications constitute the first, second, and third revolution in psychiatry, respectively. Addressing comorbidities of mental illnesses with chronic physical illnesses will be the fourth revolution in psychiatry. Mind and body are inseparable; there is a bidirectional relationship between psyche and soma, each influencing the other. Plausible biochemical explanations are appearing at an astonishing rate. Psychiatric comorbidity with many chronic physical disorders has remained neglected. Such comorbidity with cardiac, respiratory, Gastrointestinal, endocrinal, and neurological disorders, trauma, and other conditions like HIV and so on, needs to be addressed too. Evidence base of prevalence and causal relationship of psychiatric comorbidities in these disorders has been highlighted and strategies to meet the challenge of comorbidity have been indicated.

A multilevel model for cardiovascular disease prevalence in the US and its application to micro area prevalence estimates

Congdon Peter

2009-01-01

Full Text Available Abstract Background Estimates of disease prevalence for small areas are increasingly required for the allocation of health funds according to local need. Both individual level and geographic risk factors are likely to be relevant to explaining prevalence variations, and in turn relevant to the procedure for small area prevalence estimation. Prevalence estimates are of particular importance for major chronic illnesses such as cardiovascular disease. Methods A multilevel prevalence model for cardiovascular outcomes is proposed that incorporates both survey information on patient risk factors and the effects of geographic location. The model is applied to derive micro area prevalence estimates, specifically estimates of cardiovascular disease for Zip Code Tabulation Areas in the USA. The model incorporates prevalence differentials by age, sex, ethnicity and educational attainment from the 2005 Behavioral Risk Factor Surveillance System survey. Influences of geographic context are modelled at both county and state level, with the county effects relating to poverty and urbanity. State level influences are modelled using a random effects approach that allows both for spatial correlation and spatial isolates. Results To assess the importance of geographic variables, three types of model are compared: a model with person level variables only; a model with geographic effects that do not interact with person attributes; and a full model, allowing for state level random effects that differ by ethnicity. There is clear evidence that geographic effects improve statistical fit. Conclusion Geographic variations in disease prevalence partly reflect the demographic composition of area populations. However, prevalence variations may also show distinct geographic 'contextual' effects. The present study demonstrates by formal modelling methods that improved explanation is obtained by allowing for distinct geographic effects (for counties and states and for

Full Text Available Abstract Background This study describes the prevalence of dementia and major dementia subtypes in Spanish elderly. Methods We identified screening surveys, both published and unpublished, in Spanish populations, which fulfilled specific quality criteria and targeted prevalence of dementia in populations aged 70 years and above. Surveys covering 13 geographically different populations were selected (prevalence period: 1990-2008. Authors of original surveys provided methodological details of their studies through a systematic questionnaire and also raw age-specific data. Prevalence data were compared using direct adjustment and logistic regression. Results The reanalyzed study population (aged 70 year and above was composed of Central and North-Eastern Spanish sub-populations obtained from 9 surveys and totaled 12,232 persons and 1,194 cases of dementia (707 of Alzheimer's disease, 238 of vascular dementia. Results showed high variation in age- and sex-specific prevalence across studies. The reanalyzed prevalence of dementia was significantly higher in women; increased with age, particularly for Alzheimer's disease; and displayed a significant geographical variation among men. Prevalence was lowest in surveys reporting participation below 85%, studies referred to urban-mixed populations and populations diagnosed by psychiatrists. Conclusion Prevalence of dementia and Alzheimer's disease in Central and North-Eastern Spain is higher in females, increases with age, and displays considerable geographic variation that may be method-related. People suffering from dementia and Alzheimer's disease in Spain may approach 600,000 and 400,000 respectively. However, existing studies may not be completely appropriate to infer prevalence of dementia and its subtypes in Spain until surveys in Southern Spain are conducted.

Full Text Available OBJECTIVES: To estimate prevalence of chronic conditions among patients seeing a general practitioner (GP, patients attending general practice at least once in a year, and the Australian population. DESIGN SETTING AND PARTICIPANTS: A sub-study of the BEACH (Bettering the Evaluation and Care of Health program, a continuous national study of general practice activity conducted between July 2008 and May 2009. Each of 290 GPs provided data for about 30 consecutive patients (total 8,707 indicating diagnosed chronic conditions, using their knowledge of the patient, patient self-report, and patient's health record. MAIN OUTCOME MEASURES: Estimates of prevalence of chronic conditions among patients surveyed, adjusted prevalence in patients who attended general practice at least once that year, and national population prevalence. RESULTS: Two-thirds (66.3% of patients surveyed had at least one chronic condition: most prevalent being hypertension (26.6%, hyperlipidaemia (18.5%, osteoarthritis (17.8%, depression (13.7%, gastro-oesophageal reflux disease (11.6%, asthma (9.5% and Type 2 diabetes (8.3%. For patients who attended general practice at least once, we estimated 58.8% had at least one chronic condition. After further adjustment we estimated 50.8% of the Australian population had at least one chronic condition: hypertension (17.4%, hyperlipidaemia (12.7%, osteoarthritis (11.1%, depression (10.5% and asthma (8.0% being most prevalent. CONCLUSIONS: This study used GPs to gather information from their knowledge, the patient, and health records, to provide prevalence estimates that overcome weaknesses of studies using patient self-report or health record audit alone. Our results facilitate examination of primary care resource use in management of chronic conditions and measurement of prevalence of multimorbidity in Australia.

Steep-slope transistors allow to scale down the supply voltage and the energy per computed bit of information as compared to conventional field-effect transistors (FETs), due to their sub-60 mV/decade subthreshold swing at room temperature. Currently pursued approaches to achieve such a subthermionic subthreshold swing consist in alternative carrier injection mechanisms, like quantum mechanical band-to-band tunneling (BTBT) in Tunnel FETs or abrupt phase-change in metal-insulator transition (MIT) devices. The strengths of the BTBT and MIT have been combined in a hybrid device architecture called phase-change tunnel FET (PC-TFET), in which the abrupt MIT in vanadium dioxide (VO 2 ) lowers the subthreshold swing of strained-silicon nanowire TFETs. In this work, we demonstrate that the principle underlying the low swing in the PC-TFET relates to a sub-unity body factor achieved by an internal differential gate voltage amplification. We study the effect of temperature on the switching ratio and the swing of the PC-TFET, reporting values as low as 4.0 mV/decade at 25 °C, 7.8 mV/decade at 45 °C. We discuss how the unique characteristics of the PC-TFET open new perspectives, beyond FETs and other steep-slope transistors, for low power electronics, analog circuits and neuromorphic computing.

Omomia, O. Austin

2014-07-01

Full Text Available Abrahamic faiths refer to the three most popular religions that traced their origin to Abraham. These religions are Judaism (the earliest of the three, Christianity and Islam (Islam is commonly adjudged as the most recent.This paper examined the common worship, customs and other religious ceremonies prevalent among the Abrahamic faiths. It also identified the common areas of agreement between the Abrahamic faiths with regards to the common religious related customs. It is on this strength that the paper argued that the Abrahamic faiths should emphasize on areas of unity rather than widen the gulf of disagreement. The paper employed the historical and sociological methods of investigation. It is recommended that the Abrahamic faiths should explore areas of unity in order to strengthen the cord of tolerance and peace in the world in general and Nigeria in particular.

High baseline autism spectrum disorder prevalence estimates in New Jersey led to a follow-up surveillance. The objectives were to determine autism spectrum disorder prevalence in the year 2006 in New Jersey and to identify changes in the prevalence of autism spectrum disorder or in the characteristics of the children with autism spectrum disorder, between 2002 and 2006. The cohorts included 30,570 children, born in 1998 and 28,936 children, born in 1994, residing in Hudson, Union, and Ocean counties, New Jersey. Point prevalence estimates by sex, ethnicity, autism spectrum disorder subtype, and previous autism spectrum disorder diagnosis were determined. For 2006, a total of 533 children with autism spectrum disorder were identified, consistent with prevalence of 17.4 per 1000 (95% confidence interval = 15.9-18.9), indicating a significant increase in the autism spectrum disorder prevalence (p autism spectrum disorder was broad, affecting major demographic groups and subtypes. Boys with autism spectrum disorder outnumbered girls by nearly 5:1. Autism spectrum disorder prevalence was higher among White children than children of other ethnicities. Additional studies are needed to specify the influence of better awareness of autism spectrum disorder prevalence estimates and to identify possible autism spectrum disorder risk factors. More resources are necessary to address the needs of individuals affected by autism spectrum disorder.

Full Text Available BACKGROUND: Understanding the prevalence of schizophrenia has important implications for both health service planning and risk factor epidemiology. The aims of this review are to systematically identify and collate studies describing the prevalence of schizophrenia, to summarize the findings of these studies, and to explore selected factors that may influence prevalence estimates. METHODS AND FINDINGS: Studies with original data related to the prevalence of schizophrenia (published 1965-2002 were identified via searching electronic databases, reviewing citations, and writing to authors. These studies were divided into "core" studies, "migrant" studies, and studies based on "other special groups." Between- and within-study filters were applied in order to identify discrete prevalence estimates. Cumulative plots of prevalence estimates were made and the distributions described when the underlying estimates were sorted according to prevalence type (point, period, lifetime, and lifetime morbid risk. Based on combined prevalence estimates, the influence of selected key variables was examined (sex, urbanicity, migrant status, country economic index, and study quality. A total of 1,721 prevalence estimates from 188 studies were identified. These estimates were drawn from 46 countries, and were based on an estimated 154,140 potentially overlapping prevalent cases. We identified 132 core studies, 15 migrant studies, and 41 studies based on other special groups. The median values per 1,000 persons (10%-90% quantiles for the distributions for point, period, lifetime, and lifetime morbid risk were 4.6 (1.9-10.0, 3.3 (1.3-8.2, 4.0 (1.6-12.1, and 7.2 (3.1-27.1, respectively. Based on combined prevalence estimates, we found no significant difference (a between males and females, or (b between urban, rural, and mixed sites. The prevalence of schizophrenia in migrants was higher compared to native-born individuals: the migrant-to-native-born ratio median (10

Using data from the 2002-2003 National Assessment Performance Survey, the prevalence of depression was estimated at the national level, by sex, age, education, size of residence community, and state. The percentage of individuals with medically diagnosed depression and the percentage of those under treatment were also estimated. The national prevalence of depression was 4.5%: 5.8% in women and 2.5% in men. The prevalence of depression increased with age and decreased with higher education. Among males, the prevalence was higher in rural than urban communities. A large percentage of affected individuals have no medical diagnosis. Depression is a frequent disease in adults.A higher prevalence is associated with social vulnerability. The low percentage of diagnosis represents a challenge for mental health service planning and provision.

Although obesity disparities between racial and socioeconomic groups have been well characterized, those based on gender and geography have not been as thoroughly documented. This study describes obesity prevalence by state, gender, and race and/or ethnicity to (1) characterize obesity gender inequality, (2) determine if the geographic distribution of inequality is spatially clustered, and (3) contrast the spatial clustering patterns of obesity gender inequality with overall obesity prevalence. Data from the Centers for Disease Control and Prevention's 2013 Behavioral Risk Factor Surveillance System were used to calculate state-specific obesity prevalence and gender inequality measures. Global and local Moran's indices were calculated to determine spatial autocorrelation. Age-adjusted, state-specific obesity prevalence difference and ratio measures show spatial autocorrelation (z-score = 4.89, P-value obesity prevalence and obesity gender inequalities are not the same. High and low values of obesity prevalence and gender inequalities cluster in different areas of the United States. Clustering of gender inequality suggests that spatial processes operating at the state level, such as occupational or physical activity policies or social norms, are involved in the etiology of the inequality and necessitate further attention to the determinates of obesity gender inequality.

The oil policies of the Gulf Arab Nations

Energy Technology Data Exchange (ETDEWEB)

Ripple, R.D.; Hagen, R.E.

1995-03-01

At its heart, Arab oil policy is inseparable from Arab economic and social policy. This holds whether we are talking about the Arab nations as a group or each separately. The seven Arab nations covered in this report-Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates--participate in several organizations focusing on regional cooperation regarding economic development, social programs, and Islamic unity, as well as organizations concerned with oil policies. This report focuses on the oil-related activities of the countries that may reveal the de facto oil policies of the seven Persian Gulf nations. Nevertheless it should be kept in mind that the decision makers participating in the oil policy organizations are also involved with the collaborative efforts of these other organizations. Oil policies of five of the seven Arab nations are expressed within the forums of the Organization of Petroleum Exporting Countries (OPEC) and the Organization of Arab Petroleum Exporting Countries (OAPEC). Only Oman, among the seven, is not a member of either OAPEC or OPEC; Bahrain is a member of OAPEC but not of OPEC. OPEC and OAPEC provide forums for compromise and cooperation among their members. Nevertheless, each member state maintains its own sovereignty and follows its own policies. Each country deviates from the group prescription from time to time, depending upon individual circumstances.

There are limited data available on the prevalence of stroke in the United Kingdom. Such data are important for the assessment of the health needs of the population. This study aimed to determine the prevalence of stroke and the prevalence of associated dependence in a district of northern England. This was a two-stage point prevalence study. A valid screening questionnaire was used to identify stroke survivors from an age- and sex-stratified sample of the population aged 45 years and over in a family health services authority district. This was followed by assessment of stroke patients with scales of disability and handicap. The overall prevalence of stroke was found to be 17.5/1000 (95 per cent confidence interval (CI) 17.0, 18.0). The prevalence of stroke-associated dependence was 11.7/1000 (95 per cent CI 11.3, 12.1). Self-reported comorbidity was most commonly due to circulatory and musculoskeletal disorders. The prevalence of stroke in this district is considerably higher than current guidelines and previous results suggest. Nevertheless, the result from this study combined with that from a previous study in another district in the United Kingdom should allow those interested in epidemiologically based health needs assessment to make reasonable estimates of the burden of stroke in their area.

Background Many small studies have been done in Honduras estimating soil-transmitted helminthiasis (STH) prevalence but a country-wide study was last done in 2005. The country has the highest burden of malaria among all Central American countries. The present study was done to estimate country-wide STH prevalence and intensity, malaria prevalence and nutritional status in school going children. Methods and Findings A cross-sectional study was conducted following PAHO/WHO guidelines to select a sample of school going children of 3rd to 5th grades, representative of ecological regions in the country. A survey questionnaire was filled; anthropometric measurements, stool sample for STH and blood sample for malaria were taken. Kato-Katz method was used for STH prevalence and intensity and rapid diagnostic tests, microscopy, and polymerase chain reaction (PCR) were used for malaria parasite detection. A total of 2554 students were studied of which 43.5% had one or more STH. Trichuriasis was the most prevalent (34%) followed by ascariasis (22.3%) and hookworm (0.9%). Ecological regions II (59.7%) and VI (55.6%) in the north had the highest STH prevalence rates while IV had the lowest (10.6%). Prevalence of one or more high intensity STH was low (1.6%). Plasmodium vivax was detected by PCR in only 5 students (0.2%), all of which belonged to the same municipality; no P. falciparum infection was detected. The majority of children (83%) had normal body mass index for their respective age but a significant proportion were overweight (10.42%) and obese (4.35%). Conclusions Biannual deworming campaigns would be necessary in ecological regions II and VI, where STH prevalence is >50%. High prevalence of obesity in school going children is a worrying trend and portends of future increase in obesity related diseases. Malaria prevalence, both symptomatic and asymptomatic, was low and provides evidence for Honduras to embark on elimination of the disease. PMID:25330010

[Manpower migrations and Arab unity: the challenges of the Iraqi model].

Science.gov (United States)

Roussillon, A

1985-01-01

the presence of large numbers of foreign workers not only to the countries employing them but to the Arab nation as a whole allows Iraq to criticize the migration policies of the Gulf oil exporters, which are increasingly favoring more productive labor from Asian countries and which cede much of the authority to select and admit workers to private concerns. The evolution of Iraq's policy demonstrates the concern of its governing party with reconciling its Arab identity and its analysis of international power relations with consolidation of its own position internally and in the Arab world as a whole. The labor policy of the oil exporters exposes their countries and thus the Arab world to the possibility of sabotage and to demographic overpowering of ethnic and cultural identity. Interpretations differ as to whether the Iraqi model has led to a better deployment of labor and as to its theoretical contribution to pan-Arab unity, given the diverging interests of the individual states concerned.

We conducted an ecological study of data from COPD prevalence articles to assess the influence of differences in country-level risk factors on COPD prevalence. Patients and methods: Our study covered English language articles published during 2003–2014. Qualified articles used spirometry to assess COPD prevalence and used representative samples from national or subnational populations. Stepwise binomial regression was used to analyze associations between study- and country-level factors and COPD prevalence. Results: Eighty articles provided 1,583 measures of COPD prevalence for subjects in different sex, age, and smoking categories for 112 districts in 41 countries. Adjusted prevalence rates for COPD were significantly lower for Australia/New Zealand and the Mediterranean and significantly higher for Latin America, compared to North America, Southeast Asia, and Northern Europe. Country-level socioeconomic development variables had an uneven and mixed association with COPD prevalence. High elevation above sea level was shown to be a protective factor for COPD. Study-level variables for the established risk factors of sex, age, and smoking explained 64% of variability in COPD prevalence. Country-level risk factors raised the explanatory power to 72%. Approximately 28% of worldwide variability in COPD prevalence remained unexplained. Conclusion: Our study suggests that COPD prevalence varies across world regions, even after adjustment for established risk factors. Major country-level risk factors contributing to the worldwide epidemic of COPD remain

Smoking prevalence: a comparison of two American surveys.

To compare smoking prevalence estimates from two nationally representative surveys in the USA. Smoking prevalence estimates derived from the National Health Interview Survey (NHIS) and the National Survey on Drug Use and Health (NSDUH) for the period 1998-2005. Comparisons according to age (18-34 or 35+ years) and according to smoking frequency (every day or some days). In 1998, the prevalence of smoking in both surveys was nearly identical at 24%. From 1999 to 2005, a divergence occurred in smoking prevalence found by the NSDUH and the NHIS. By 2005, NHIS prevalence had declined to 20.9% [95% confidence interval (CI) 20.3-21.5], but the NSDUH estimate was 25.4% (95%CI 24.6-26.2), amounting to 9.1 million more smokers. In 1999, prevalence among 18-34 year olds in the NSDUH was only 18% (95%CI 13-22) higher than that in the NHIS, but that difference had doubled by 2005, when smoking prevalence among 18-34 year olds was 36% (95%CI 30-41) higher in the NSDUH than in the NHIS. NSDUH and NHIS prevalence among 35+ year olds were similar in 1999 and 2001, but the difference was 13% (95%CI 9-18) in 2005. Higher smoking prevalence estimates in the NSDUH were largely due to much higher estimates for some-day smoking in that survey, although every-day smoking prevalence among 18-34 year-olds was also higher in the NSDUH than in the NHIS. These results raise doubt about the recent decline in smoking prevalence described by the NHIS. Further investigation of the NSDUH/NHIS discrepancy may lead to better surveys and to a clearer picture of smoking trends in the USA.

Burnout is a job-related psychological syndrome with three aspects: emotional exhaustion, depersonalization, and perceived lack of personal accomplishment. Burnout is associated with deleterious effects on both workers and their work. When burnout affects physicians, their well-being, longevity, and care of patients are at risk. Recent studies concerning physician burnout treat specialists such as radiologists as one group. We studied burnout in musculoskeletal (MSK) subspecialist radiologists. An institutional review board exemption was obtained. Society of Skeletal Radiology members received invitations to an anonymous survey that included questions from the Maslach Burnout Inventory trademark (MBI) measuring all three aspects of burnout. The response rate was 36.4% (433/1190). The prevalence of emotional exhaustion was 61.7% (255/413), of depersonalization 53.3% (219/411), and of perceived lack of personal accomplishment 39.6% (161/407). Only 19.5% (79/405) of MSK radiologists reported no burnout, while 80.5% (326/405) reported burnout along one or more dimensions. For all three dimensions, the prevalence was higher and the mean severity was worse for private practice compared with academic practice. The prevalence of burnout was affected more by practice setting than by gender. Burnout prevalence and severity also varied systematically with years since completion of training. Among MSK radiologists, we found a much higher prevalence and greater severity of burnout than has been previously reported for radiologists and other physicians. There were differences in prevalence and severity of burnout among practice settings, genders, and longevity cohorts. (orig.)

Full Text Available Objective:To study the prevalence and demographic characteristics of mood disorders among Iranian adults. Method: In this cross-sectional population-based epidemiological study (age > 18 in Iran, 25180 individuals were selected through a randomized cluster sampling method for a diagnosis using the Schedule for Affective Disorders and Schizophrenia (SADS. They were then interviewed at home by 250 trained clinical psychologists. Results: The estimated lifetime prevalence of Major Depressive Disorder (MDD and Minor Depressive Disorder (mDD were 3.1% and 0.3% respectively. Also, the estimated lifetime prevalence of Bipolar Mood disorder (BMD type I and type II were 0.1% and 0.7% respectively. The current prevalence of MDD, mDD, BMD-I, and BMD-II were 1.8%, 0.2%, 0.04%, and 0.3% respectively. Mood disorders were associated with female gender, lower education, being married, being middle-aged, living in cities, and not being a homemaker. Conclusion: The prevalence of mood disorders was lower among Iranian adults than reported in Western studies, and a number of demographic associations differed from those reported in Western studies. Important cultural differences in the nature or manifestation of depression are implied by these results.

ABSTRACT Introduction: This study sought to estimate the global prevalence of transthyretin familial amyloid polyneuropathy (ATTR‐FAP). Methods: Prevalence estimates and information supporting prevalence calculations was extracted from records yielded by reference‐database searches (2005–2016), conference proceedings, and nonpeer reviewed sources. Prevalence was calculated as prevalence rate multiplied by general population size, then extrapolated to countries without prevalence estimates but with reported cases. Results: Searches returned 3,006 records; 1,001 were fully assessed and 10 retained, yielding prevalence for 10 “core” countries, then extrapolated to 32 additional countries. ATTR‐FAP prevalence in core countries, extrapolated countries, and globally was 3,762 (range 3639–3884), 6424 (range, 1,887–34,584), and 10,186 (range, 5,526–38,468) persons, respectively. Discussion: The mid global prevalence estimate (10,186) approximates the maximum commonly accepted estimate (5,000–10,000). The upper limit (38,468) implies potentially higher prevalence. These estimates should be interpreted carefully because contributing evidence was heterogeneous and carried an overall moderate risk of bias. This highlights the requirement for increasing rare‐disease epidemiological assessment and clinician awareness. Muscle Nerve 57: 829–837, 2018 PMID:29211930

There is scarce data about NMOSD prevalence in South East Asian populations. (1) A population-based study was undertaken to estimate NMOSD prevalence in the multi-ethnic Penang Island, Malaysia, comprising Chinese, Malays, and Indians. Medical records of NMOSD patients followed up at the Penang General Hospital (the neurology referral centre in Penang Island) were reviewed. The 2015 diagnostic criteria of the International Panel for NMO Diagnosis were used for case ascertainment. (2) A review of population-based prevalence studies of NMOSD worldwide was carried out. PubMed and conference proceedings were searched for such studies. Of the 28 NMOSD patients, 14 were residents of Penang Island on prevalence day [13 (93%) Chinese and one (7%) Malay]. All 14 patients were females and aquaporin 4 seropositive. The prevalence of NMOSD in Penang Island was 1.99/100,000 population; according to ethnicities, the prevalence in Chinese was significantly higher than in Malays (3.31/100,000 vs 0.43/100,000, respectively, p = 0.0195). Based on our and other population-based studies, among Asians, East Asian origin populations (Chinese and Japanese) appear to have higher NMOSD prevalence than other Asian ethnic groups. Worldwide, Blacks seem to have the highest NMOSD prevalence. More studies in different geographical regions and ethnic groups will be useful to further inform about potential factors in NMOSD pathogenesis. Copyright © 2017 Elsevier B.V. All rights reserved.

Glenohumeral arthritis secondary to massive rotator cuff tear presents with a superior displacement and femoralization of the humeral head with coracoacromial arch acetabularization. The purpose of this study was to establish prevalence of rotator cuff tear artropathy (CTA) at our institution. Four hundred electronic records were reviewed from which we identified 136 patients with rotator cuff tears. A second group was composed with patients with massive cuff tears that were analized and staged by the Seebauer cuff tear arthropathy classification. Thirty four patients with massive rotator cuff tears were identified, 8 male and 26 female (age 60.1 ± 10.26 years). Massive rotator cuff tear prevalence was 25%. CTA prevalence found in the rotator cuff group was 19 and 76% in the massive cuff tears group. Patients were staged according to the classification with 32% in stage 1a, 11% 1b, 32% 2a and 0% 2b. CTA prevalence in patients with rotator cuff tears and massive cuff tears is higher than the one reported in American population. We consider that a revision of the Seebauer classification to be appropriate to determine its reliability.

Prevalence of blood parasites in seabirds - a review

2011-10-01

Full Text Available Abstract Introduction While blood parasites are common in many birds in the wild, some groups seem to be much less affected. Seabirds, in particular, have often been reported free from blood parasites, even in the presence of potential vectors. Results From a literature review of hemosporidian prevalence in seabirds, we collated a dataset of 60 species, in which at least 15 individuals had been examined. These data were included in phylogenetically controlled statistical analyses of hemosporidian prevalence in relation to ecological and life-history parameters. Haemoproteus parasites were common in frigatebirds and gulls, while Hepatozoon occurred in albatrosses and storm petrels, and Plasmodium mainly in penguins. The prevalence of Haemoproteus showed a geographical signal, being lower in species with distribution towards polar environments. Interspecific differences in Plasmodium prevalence were explained by variables that relate to the exposure to parasites, suggesting that prevalence is higher in burrow nesters with long fledgling periods. Measures of Plasmodium, but not Haemoproteus prevalences were influenced by the method, with PCR-based data resulting in higher prevalence estimates. Conclusions Our analyses suggest that, as in other avian taxa, phylogenetic, ecological and life-history parameters determine the prevalence of hemosporidian parasites in seabirds. We discuss how these relationships should be further explored in future studies.

We examined the prevalence of PDB in Italy from radiological, scintigraphic, and biochemical surveys in two Italian towns. Prevalence rates varied from 0.7% to 2.4%, were higher in males than in females, and slightly differed between the two towns. Unlike previous studies in populations of British descent, no secular trend for a decreasing prevalence emerged. Clinical, radiological, and necropsy data from different countries suggested pronounced geographical variations in the prevalence of Paget's disease of bone (PDB). Despite the impact of the disease on the population, there are limited data on the prevalence of PDB in Italy. The objective of this study was to estimate the prevalence of PDB in the district of Siena (Central Italy) and Turin (Northern Italy) from radiological, biochemical, and scintigraphic surveys. We examined a sample of 1778 consecutive pelvic radiographs performed between 1999 and 2000 at the Hospital Radiology Unit in Siena and 6609 pelvic radiographs performed in 1986-1987, 1992-1993, and 1999-2002 from the Radiology Department of Molinette Hospital in Turin. In Siena, 7906 consecutive (99m)TC-MDP bone scans performed over a 4-year period (January 2000 to May 2004) were also screened for the presence of PDB, and the prevalence of elevated alkaline phosphatase (ALP) levels (>300 UI/liter) was estimated from 7449 computerized medical records over a 3-year period (January 2000 to February 2003). The finding of PDB on the pelvic radiograph and bone scan was based on standardized radiological criteria. At the end of the radiological surveys, 16/1778 pelvic PDB cases (8 males and 8 females) were observed in Siena and 41/6609 (27 males and 14 females) in Turin. The crude prevalence of the disease was 0.89% in Siena and 0.62% in Turin. Given that pelvic involvement is commonly described in 60-90% of PDB patients, the estimated overall prevalence of PDB ranged from 1.0% to 1.5% in Siena and from 0.7% to 1.0% in Turin. No decrease in the prevalence

Developmental anomalies of the dentition are not infrequently observed by the dental practitioner. The aim of the present study was to determine the prevalence of dental anomalies in the Indian population. A retrospective study of 4133 panoramic radiographs of patients, who attended the Department of Oral Medicine and Radiology, Jodhpur Dental College General Hospital between September 2008 to December 2012 was done. The ages of the patients ranged from 13 to 38 years with a mean age of 21.8 years. The orthopantomographs (OPGs) and dental records were examined for any unusual finding such as congenitally missing teeth, impactions, ectopic eruption, supernumerary teeth, odontoma, dilacerations, taurodontism, dens in dente, germination and fusion, among others. 1519 (36.7%) patients had at least one dental anomaly. The congenitally missing teeth 673 (16.3%) had the highest prevalence, followed by impacted teeth 641 (15.5%), supernumerary teeth 51 (1.2%) and microdontia 41 (1.0%). Other anomalies were found at lower prevalence ranging from transposition 7 (0.1%) to ectopic eruption 30 (0.7%). The most prevalent anomaly in the Indian population was congenitally missing teeth (16.3%), and the second frequent anomaly was impacted teeth (15.5%), whereas, macrodontia, odontoma and transposition were the least frequent anomalies, with a prevalence of 0.2%, 0.2% and 0.1% respectively. While the overall prevalence of these anomalies may be low, the early diagnosis is imperative for the patient management and treatment planning. Key words:Dental anomaly, prevalence, panoramic radiography.

Full Text Available Ethics and trust can avoid crises, just as, as recent events have clearly proved, the reverse is true. The paper is simply constructed: Section 1 provides a historical analysis; Section 2 deals with today‟s situation, drawing similarities and differences and the possible outcomes thereby arising; the final section concludes. Historical data are difficult to come by for most countries, especially when they should also be comparable across time. In general, and for this reason, US data have been used: however, the situation in other countries was little different, as will be shown, so that the data may be considered to be representative.

Endoscopy and sedation: an inseparable binomial for the gastroenterologist.

Science.gov (United States)

Crespo, Javier; Terán, Álvaro

2018-04-01

The development of endoscopy and its increasing demand among the population have led to a growing need for propofol-based sedation techniques. Benefit is indisputable for both patients and endoscopists, but some aspects require considering the "who" and "how" of sedation as related to safety and health care costs. Propofol is first-choice in endoscopy for the European Society of Gastrointestinal Endoscopy because of its fast onset of action and short half-life, and many reports exist on its safety when used by gastroenterologists rather than anesthesiologists. In this issue of REED several originals support the efficiency and safety of propofol even for complex, high-risk, or protracted procedures such as endoscopic retrograde cholangiopancreatography (ERCP) and enteroscopy. Propofol may be safely and effectively administered by a team with specific skills acquired through education and using a specific procedure. However, difficulties arise in real-world clinical practice that preclude such training, which in Spain should be included in the MIR (médico interno residente) specialization program curriculum. The Comisión Nacional de Digestivo (Spanish National Commission on Digestive Diseases), sensitive to this training gap, has included in their latest version of the MIR program (under assessment) four additional competences, with number 145 (training in deep sedation) being most relevant here. In addition, the Spanish Society of Gastrointestinal Endoscopy (SEED) has invested significant efforts in sedation training, with over 50 courses on sedation for endoscopists and nurses. Continuing education and training in this field (for instance, refresher courses on advanced cardiopulmonary resuscitation) should be a goal for all endoscopy units. Because of the diversity found among hospitals, with single or multiple endoscopy rooms, efforts should be made to persuade those in charge of gastroenterology and anesthesiology departments to establish the necessary care circuits in order to guarantee patient safety by developing accurate protocols and promoting consensus among the scientific societies involved (Spanish Society for Digestive Diseases [SEPD], SEED and Spanish Society of Anaesthesiology, Resuscitation and Pain Management [SEDAR]) and their respective national commissions.

Inseparability inequalities for higher order moments for bipartite systems

International Nuclear Information System (INIS)

Agarwal, G S; Biswas, Asoka

2005-01-01

There are several examples of bipartite entangled states of continuous variables for which the existing criteria for entanglement using the inequalities involving the second-order moments are insufficient. We derive new inequalities involving higher order correlation, for testing entanglement in non-Gaussian states. In this context, we study an example of a non-Gaussian state, which is a bipartite entangled state of the form Ψ(x a , x b ) ∝ (αx a + βx b ) e -(x a 2 +x b 2 )/2 . Our results open up an avenue to search for new inequalities to test entanglement in non-Gaussian states

Nasser M Al-Daghri

Full Text Available A decade has passed since metabolic syndrome (MetS was documented to be highly prevalent in the kingdom of Saudi Arabia. No follow-up epidemiologic study was done. This study aims to fill this gap. In this cross-sectional, observational study, a total of 2850 randomly selected Saudi adults aged 18-55 years were recruited. Subjects' information was generated from a database of more than 10,000 Saudi citizens from the existing Biomarkers Screening in Riyadh Program (RIYADH Cohort, Saudi Arabia. Anthropometrics included body mass index (BMI, blood pressure, as well as waist and hip circumferences. Fasting blood glucose and lipid profile were determined using routine laboratory procedures. The definition of ATP-III (NHANES III was used for the diagnosis of the full MetS. The overall prevalence of complete MetS was 35.3% [Confidence-Interval (CI 33.5-37.01]. Age-adjusted prevalence according to the European standard population is 37.0%. Low HDL-cholesterol was the most prevalent of all MetS risk factors, affecting 88.6% (CI 87.5-89.7 and hypertriglyceridemia the second most prevalent, affecting 34% (CI 32.3-35.7 of the subjects. The prevalence of the full MetS decreased from previous estimates but remains high, while dyslipidemia remains extremely high, affecting almost 90% of middle-aged Arabs. Screening for dyslipidemia among Saudi adults is warranted, especially among those most at risk. Scientific inquiry into the molecular causes of these manifestations should be pursued as a first step in the discovery of etiologic therapies.

ABSTRACT OBJECTIVE To estimate the prevalences of tobacco use, tobacco experimentation, and frequent smoking among Brazilian adolescents. METHODS We evaluated participants of the cross-sectional, nation-wide, school-based Study of Cardiovascular Risks in Adolescents (ERICA), which included 12- to 17-year-old adolescents from municipalities of over 100 thousand inhabitants. The study sample had a clustered, stratified design and was representative of the whole country, its geographical regions, and all 27 state capitals. The information was obtained with self-administered questionnaires. Tobacco experimentation was defined as having tried cigarettes at least once in life. Adolescents who had smoked on at least one day over the previous 30 days were considered current cigarette smokers. Having smoked cigarettes for at least seven consecutive days was an indicator for regular consumption of tobacco. Considering the complex sampling design, prevalences and 95% confidence intervals were estimated according to sociodemographic and socio-environmental characteristics. RESULTS We evaluated 74,589 adolescents. Among these, 18.5% (95%CI 17.7-19.4) had smoked at least once in life, 5.7% (95%CI 5.3-6.2) smoked at the time of the research, and 2.5% (95%CI 2.2-2.8) smoked often. Adolescents aged 15 to 17 years had higher prevalences for all indicators than those aged 12 to 14 years. The prevalences did not differ significantly between sexes. The highest prevalences were found in the South region and the lowest ones, in the Northeast region. Regardless of sex, the prevalences were found to be higher for adolescents who had had paid jobs, who lived with only one parent, and who reported having been in contact with smokers either inside or outside their homes. Female public school adolescents were found to smoke more than the ones from private schools. CONCLUSIONS Tobacco use among adolescents is still a challenge.

Prevalence of breast arterial calcification in hypertensive patients

International Nuclear Information System (INIS)

Cetin, M.; Cetin, R.; Tamer, N.

2004-01-01

AIM: To determine the age-specific prevalence of breast arterial calcifications in patients with systemic hypertension. METHODS: The mammograms and patient records of 2406 women who underwent screening or diagnostic mammography were reviewed retrospectively. Mammograms were evaluated for the presence of arterial calcification and results were coded. Hypertension was defined as use of anti-hypertensive agents and diabetes was defined as use of oral hypoglycaemic agents or insulin. RESULTS: The prevalence of breast arterial calcification among hypertensives (17.6%) was lower than among diabetics (25.4%). The prevalence in the non-diabetic, non-hypertensive group was lowest (7.3%). The prevalence increased with age in all three groups. The highest prevalence was found in diabetics older than 60 years (81.8%). Breast arterial calcification was not found among women younger than 40 years. CONCLUSION: Breast arterial calcification is associated with hypertension and prevalence increases with age. Breast arterial calcification on mammograms may indicate unsuspected hypertension especially in non-diabetic patients

Full Text Available From a purely educationist perspective, gaining a deeper understanding of several aspects related to the prevalence of autism/ASD in a given population is of great value in planning and improving educational and psychological intervention for treatment, training, and teaching of children with this disorder. In this article, I present and discuss numerous facets of prevalence studies, beginning with assessing the changes in diagnostic manuals (DSM and ICD over time. Based on the existing available research literature and empirical studies published during 2000 to 2016, I address the geographical-dimension and age-dimension of prevalence of autism/ASD. Over 50 studies from 21 countries reveals that prevalence rates of autism/ASD among children are on rise. There are inter-national and intra-national, regional/territorial variations with regard to prevalence rates, and I present and discuss possible factors/factor-groups that can explain these variations. Regardless of their geographic location, children with autism/ASD can be treated, trained, and taught, but to do so effectively requires reliable prevalence studies that can properly inform policy makers and higher institutions about the steps that must be taken in the field in order to improve the learning conditions of these children with special needs. Moving forward, it’s essential that studies of geographical dimension and age dimension of prevalence of autism/ASD must be supplemented by other (i.e. gender, socio-economic, ethnic, cultural, and language dimensions to help give us the perspective we need to grapple with this increasingly common disorder.

Oppositional defiant disorder (ODD) is characterized by a pattern of negative, defiant, disobedient and hostile behavior toward authority figures. ODD is one of the most frequent reasons for clinical consultation on mental health during childhood and adolescence. ODD has a high morbidity and dysfunction, and has important implications for the future if not treated early. To determine the prevalence of ODD in schoolchildren aged 6-16 years in Castile and Leon (Spain). Population study with a stratified multistage sample, and a proportional cluster design. Sample analyzed: 1,049. Cases were defined according to DSM-IV criteria. An overall prevalence rate of 5.6% was found (95% CI: 4.2%-7%). Male gender prevalence=6.8%; female=4.3%. Prevalence in secondary education=6.2%; primary education=5.3%. No significant differences by gender, age, grade, type of school, or demographic area were found. ODD prevalence without considering functional impairment, such as is performed in some research, would increase the prevalence to 7.4%. ODD cases have significantly worse academic outcomes (overall academic performance, reading, maths and writing), and worse classroom behavior (relationship with peers, respect for rules, organizational skills, academic tasks, and disruption of the class). Castile and Leon has a prevalence rate of ODD slightly higher to that observed in international publications. Depending on the distribution by age, morbidity and clinical dysfunctional impact, an early diagnosis and a preventive intervention are required for health planning. Copyright © 2013 SEP y SEPB.

Full Text Available Objective: Study of prevalence of stuttering in Iranian bilingual societies is essential for determine the effects of linguistic factors in stuttering and therapy demands in these bilingual societies. The aim of this study is to determine the prevalence of stuttering among Javanrud’s bilingual students. Materials & Methods: In this cross- sectional, descriptive and analytical study, all of bilingual students of Javanrud’s schools were examined and in order to this purpose, teacher referral method was used for the primary screening of speech disorders at all. Essential information about speech disorders specifically stuttering had been given to teachers before this primary step. Then researcher diagnosed stuttering students based on personal interview, reading, spontaneous speech and description of serial images that tell a story in Kurdish and Persian. Data were analysed by statistical tests such as Chi-square and Logistic Regression. Results: Among 11425 bilingual students of Javanrud’s schools, 129 students were identified as stutterers. These findings indicated that overall prevalence of stuttering in this population is 1/13 percent. Among primary, guidance and high school students the prevalence of stuttering was 2/06, 0/87 and 0/5 percent respectively. Prevalence of stuttering among boys was 1/35 and among girls was 0/88 percent. An overall male/female ratio was 1/5. Prevalence of stuttering in primary, guidance and high school was differ from each other significantly (P<0/001. Prevalence of stuttering in male was higher than female significantly (P=0/034. Conclusion: Prevalence of stuttering among Javanrood’s bilingual students was higher than accepted prevalence in monolinguals (1%. Risk of being stuttering in male was higher than female.

Objective High rates of mental disorders have been reported for prison populations worldwide, particularly in low- and middle-income countries (LMICs). The present study aimed to establish prevalence rates of mental disorders in Chilean prisoners. Method A nationwide random sample of 1008 prisoners was assessed in 7 penal institutions throughout Chile. Twelve-month prevalence rates were established using the Composite International Diagnostic Interview (CIDI) and compared to the prevalence rates previously published for the general population. Results Prevalence rates were 12.2% (95% CI, 10.2-14.1) for any substance use disorder, 8.3% (6.6-10.0) for anxiety disorders, 8.1% (6.5-9.8) for affective disorders, 5.7% (4.4-7.1) for intermittent explosive disorders, 2.2% (1.4-3.2) for ADHD of the adult, and 0.8% (0.3-1.3) for non-affective psychoses. Significantly higher prevalence rates among prisoners as compared to the general population in Chile were seen for major depression (6.1% vs. 3.7% males, Z=2.58, pprison population than in the general population. One-year prevalence rates of alcohol abuse (2.3% vs. 3.9%; Z=-2.04; pprison population than in the general population. Conclusions Service provision for prison populations in Chile should acknowledge high rates of depression and illicit drug use. Overall prevalence rates are lower than reported in other LMICs. Previous research in prison populations in LMICs might have overestimated prevalence rates of mental disorders. PMID:23894415

Anecdotal evidence suggests that the sensitivity and specificity of a diagnostic test may vary with disease prevalence. Our objective was to investigate the associations between disease prevalence and test sensitivity and specificity using studies of diagnostic accuracy. We used data from 23 meta-analyses, each of which included 10-39 studies (416 total). The median prevalence per review ranged from 1% to 77%. We evaluated the effects of prevalence on sensitivity and specificity using a bivariate random-effects model for each meta-analysis, with prevalence as a covariate. We estimated the overall effect of prevalence by pooling the effects using the inverse variance method. Within a given review, a change in prevalence from the lowest to highest value resulted in a corresponding change in sensitivity or specificity from 0 to 40 percentage points. This effect was statistically significant (p disease prevalence; there was no such systematic effect for sensitivity. The sensitivity and specificity of a test often vary with disease prevalence; this effect is likely to be the result of mechanisms, such as patient spectrum, that affect prevalence, sensitivity and specificity. Because it may be difficult to identify such mechanisms, clinicians should use prevalence as a guide when selecting studies that most closely match their situation.

The prevalence of human pathogenic Yersinia enterocolitica was determined in tonsil and intestinal content samples from 388 healthy fattening pigs at the four biggest Finnish slaughterhouses. These slaughterhouses process 73% of pigs in Finland. Tonsil samples were tested by PCR targeted for yadA, and intestinal samples were cultured. All pathogenic Y. enterocolitica isolates represented bioserotype 4/O:3. The prevalence of Y. enterocolitica in tonsil samples was 60% (95% confidence limit, 55.4 to 65.1%), and its prevalence in intestinal samples was 26% (95% confidence limit, 22.1 to 31.2%). The prevalence of Y. enterocolitica in tonsil and intestinal samples varied between the four slaughterhouses. The tonsil prevalence of Y. enterocolitica was higher in slaughterhouse B, and the prevalence in intestinal content was higher in slaughterhouse C. There were more positive results in both tonsil and intestinal samples in pigs coming from fattening farms than in pigs coming from farrowing-and-fattening farms. A seasonal variation was observed in the prevalence of Y. enterocolitica in intestinal samples, with the highest prevalence during July and August, but no seasonal variation was detected in tonsil samples.

The last comparison of prevalence figures of dementia across European studies was 10 years ago. Using studies conducted in the 1990s, the authors compare the age- and sex-specific prevalence of dementia, AD, and vascular dementia (VaD) across European population-based studies of persons 65 years...... and older. Data from these studies were also pooled to obtain stable estimates of age- and sex-specific prevalence. A total of 2346 cases of mild to severe dementia were identified in 11 cohorts. Age-standardized prevalence was 6.4% for dementia (all causes), 4.4% for AD, and 1.6% for VaD. The prevalence...... of dementia increased continuously with age and was 0.8% in the group age 65 to 69 years and 28.5% at age 90 years and older. The corresponding figures for AD (53.7% of cases) were 0.6% and 22.2%, and for VaD (15.8% of cases), 0.3% and 5.2%. Variation of AD prevalence across studies was greatest for men...

Full Text Available Abstract Background Despite the heavy burden and impact of the polycystic ovary syndrome (PCOS in reproduction and public health, estimates regarding its prevalence at community levels are limited. We aimed to ascertain prevalence of PCOS in a community based sample using the National Institute of Health (NIH, the Rotterdam consensus (Rott. and the Androgen Excess Society (AES criteria. Methods Using the stratified, multistage probability cluster sampling method, 1126 women were randomly selected from among reproductive aged women of different geographic regions of Iran. PCOS were diagnosed using universal assessment of ultrasonographic parameters, hormonal profiles and clinical histories. Results The mean +/- SD of age of study population was 34.4 +/- 7.6 years. Estimated prevalence of idiopathic hirsutism was 10.9% (95% CI: 8.9-12.9%; 8.3% of women had only oligo/anovulation and 8.0% had only polycystic ovaries. The prevalence of PCOS was 7.1% (95% CI: 5.4-8.8% using the NIH definition, 11.7% (95% CI: 9.5-13.7% by AES criteria and 14.6% (95% CI: 12.3-16.9% using the Rott definition. Conclusions At community level, widespread screening of Rotterdam criteria will increase the estimated prevalence of PCOS over twofold. Establishing an explicit and contemporaneous method for definition and screening of each PCOS criteria has important investigational implications and increase the comparability of published research.

Human-induced landscape change associated with habitat loss and fragmentation places wildlife populations at risk. One issue in these landscapes is a change in the prevalence of disease which may result in increased mortality and reduced fecundity. Our understanding of the influence of habitat loss and fragmentation on the prevalence of wildlife diseases is still in its infancy. What is evident is that changes in disease prevalence as a result of human-induced landscape modification are highly variable. The importance of infectious diseases for the conservation of wildlife will increase as the amount and quality of suitable habitat decreases due to human land-use pressures. We review the experimental and observational literature of the influence of human-induced landscape change on wildlife disease prevalence, and discuss disease transmission types and host responses as mechanisms that are likely to determine the extent of change in disease prevalence. It is likely that transmission dynamics will be the key process in determining a pathogen's impact on a host population, while the host response may ultimately determine the extent of disease prevalence. Finally, we conceptualize mechanisms and identify future research directions to increase our understanding of the relationship between human-modified landscapes and wildlife disease prevalence. This review highlights that there are rarely consistent relationships between wildlife diseases and human-modified landscapes. In addition, variation is evident between transmission types and landscape types, with the greatest positive influence on disease prevalence being in urban landscapes and directly transmitted disease systems. While we have a limited understanding of the potential influence of habitat loss and fragmentation on wildlife disease, there are a number of important areas to address in future research, particularly to account for the variability in increased and decreased disease prevalence.

Full Text Available Introduction: Hypertension in pregnancy is one of the three factors of maternal mortality. Etiology of the disease is unknown, but the many factors contributing to the identification and control of it can be taken a step to prevent and reduce the symptoms of the disease. The purpose of this study was to determine the prevalence of preeclampsia (high-blood pressure in different seasons of the year. Methods: The present retrospective cross-sectional study was conducted on more than 8,000 pregnant women visiting Assali specialized hospital from 2011 to 2013. Required data was collected through questionnaire checklist. The Chi-square test with multiple comparisons was used to compare the frequencies of pregnancy-induced hypertension (PIH according to the month of year, and adjustment of multiplicity was conducted using Bonferroni's method. Student's t-test was used to compare the means of PIH prevalence rates. In all analyses, P < 0.05 was taken to indicate statistical significance. Results: In these 8000 woman admitted to labor, overall prevalence of PIH was 3.8 ± 0.6%. The prevalence rate of PIH was highest in the summer (4.5% and lowest frequent in the winter (2.7%, respectively. In July, the prevalence rate was significantly higher than those for any other month (4.7%, and in March, it was lower prevalence than for any month (2.2%, respectively. Using the Chi-square test, a significant difference between the incidence of disease was observed in summer and winter (P < 0.001. Conclusion: The prevalence rate of PIH was higher for delivery in summer and early spring and lowest for winter delivery among Khorramabad women based on these results; it seems that changes in temperature and humidity in different seasons can affect preeclampsia, and preeclampsia increases with increasing frequency temperature.

To estimate the prevalence ratios, using a log-binomial model with or without continuous covariates. Prevalence ratios for individuals' attitude towards smoking-ban legislation associated with smoking status, estimated by using a log-binomial model were compared with odds ratios estimated by logistic regression model. In the log-binomial modeling, maximum likelihood method was used when there were no continuous covariates and COPY approach was used if the model did not converge, for example due to the existence of continuous covariates. We examined the association between individuals' attitude towards smoking-ban legislation and smoking status in men and women. Prevalence ratio and odds ratio estimation provided similar results for the association in women since smoking was not common. In men however, the odds ratio estimates were markedly larger than the prevalence ratios due to a higher prevalence of outcome. The log-binomial model did not converge when age was included as a continuous covariate and COPY method was used to deal with the situation. All analysis was performed by SAS. Prevalence ratio seemed to better measure the association than odds ratio when prevalence is high. SAS programs were provided to calculate the prevalence ratios with or without continuous covariates in the log-binomial regression analysis.

The prevalence and course of pseudothrombocytopenia in outpatients is uncertain. In a cohort study of 687,955 members of a health maintenance organization, we extracted 36,780 consecutive automated complete blood count test results and determined the point prevalence of pseudothrombocytopenia during a one-month period. We also calculated a retrospective cumulative prevalence over the past 5 years. There were 1105 (2.7%) patients with platelet counts of 100-149×10(9)/L and 304 (0.8%) with counts values, or the reference limit value should be lowered to 100×10(9)/L.

The incidence of diabetes is increasing globally. We investigated the relationship between diabetes prevalence and patient socioeconomic status across multiple countries. We searched PubMed to identify population-based surveys reporting diabetes prevalence between 1990 and May 2016. Search results were filtered, and Human Development Index (HDI) values from the United Nations Development Programme were used to assess socioeconomic status for a given nation. Our analysis included 45 national surveys from 32 countries. Diabetes prevalence was positively correlated with national HDI (r = 0.421 P = 0.041) in developing countries, and negatively correlated with HDI (r = -0.442 P = 0.045) in developed countries. Diabetes prevalence trends were the same in women and men, although men were associated with increased diabetes risk in developed countries (r = 0.459 P = 0.048). Thus, diabetes prevalence rises with increasing HDI in developing countries, and this is reversed in developed countries. Ours is the first study to investigate the relationship between diabetes and socioeconomic status at global level using HDI values. These results will aid in evaluating global diabetes prevalence and risk with respect to patient socioeconomic status, and will be useful in the development of policies that help reduce disease incidence.

2010-01-01

There is no published information on the prevalence of malnutrition in Saudi Arabia. The objective of this study was to establish the prevalence data.The prevalence of nutritional indicators in the form of underweight, stunting, and wasting in a national sample of children younger than 5 years of age was calculated using the new WHO standards as reference. Calculations were performed using the corresponding WHO software. The prevalence of moderate and severe underweight, wasting and stunting, was defined as the proportion of children whose weight for age, weight for height, and height for age were below -2 and -3 standard deviation scores, respectively.The number of children younger than 5 years of age was 15 516 and 50.5% were boys. The prevalence of moderate and severe underweight was 6.9% and 1.3%, respectively. The prevalence of moderate and severe wasting was 9.8% and 2.9%, respectively. Finally, the prevalence of moderate and severe stunting was 10.9% and 2.8%, respectively. The prevalence was lower in girls for all indicators. Comparison of the prevalence of nutritional indicators in selected countries demonstrates large disparity with an intermediate position for Saudi Arabia.This report establishes the national prevalence of malnutrition among Saudi children. Compared to data from other countries, these prevalence rates are still higher than other countries with less economic resources, indicating that more efforts are needed to improve the nutritional status of children (Author).

Restless legs syndrome: relationship between prevalence and latitude.

Science.gov (United States)

Koo, Brian B

2012-12-01

Restless legs syndrome (RLS) has a broad worldwide prevalence between 0.01% and 18.3%. While differences in RLS definitions and data ascertainment methods account for some variability, other factors likely contribute. The circadian nature of RLS and the fact that RLS symptoms track with endogenous melatonin levels suggest that light or ultraviolet radiation (UVR) may be related to RLS expression. As the amount of UVR decreases with latitude, we considered the potential effect of geography on RLS prevalence with the thought being that RLS prevalence rises with increasing latitude. RLS epidemiologic studies were sought via Pubmed search in the period between January 1, 1992 and November 15, 2010. Prevalence was mapped for each country or specific region studied and examined by continent. Pearson's correlational testing was carried out for RLS prevalence and latitude of the region studied. Global RLS prevalence ranges from 0.01% in Africa, 0.7% to 12.5% in Asia, 2.0% to 18.9% in the Americas, and 3.2% to 18.3% in Europe. Mapping RLS prevalence by country or region in both the Americas and in Europe suggests increasing RLS frequency with greater northern latitude. RLS prevalence is positively correlated with northern latitude in both North America and Europe with correlation coefficients of r = 0.77 (0.15, 0.96; p = 0.02) and r = 0.74 (0.44, 0.89; p = 0.0002), respectively. In Europe, lower latitudinal countries like Greece and Turkey had RLS prevalence (per 1,000 persons) of 38 and 34, respectively, middle latitudinal countries like France and England of 108 and 86, respectively, and high latitudinal countries like Norway and Iceland of 143 and 183, respectively. RLS epidemiology indicates an increase in RLS frequency in northern latitudinal countries as a function of distance from the equator, an effect most evident in Europe. This suggests that factors that track with latitude like UVR may be involved in the expression of RLS.

Central vein stenosis (CVS) is a common complication of central venous catheter (CVC) insertion. In this study we evaluated the prevalence and risk factors of CVS among hemodialysis (HD) patients in a single center in Sudan, using Doppler ultrasound as a screening tool. The study included 106 prevalent HD patients. For every patient, we performed Duplex Doppler for the right and left jugular, subclavian and femoral veins. A patient was considered to have hemodynamically significant stenosis if the pre-stenosis to the post-stenosis velocities ratio was ≥ 2.5 or they had complete vein occlusion. Overall, 28.3% of patients had Doppler detected CVS, including 25.5% with hemodynamically significant stenosis and 2.8% with compromised flow. The prevalence of CVS was 68.4% among symptomatic patients compared to 19.5% in asymptomatic patients. The prevalence of CVS among patients with history of 0-1, 2-3 and ≥ 4 central venous catheters was 3.4%, 29.4% and 53.8% respectively (p=0.00). CVS was not more common in patients with history of previous/current jugular or femoral vein catheterization compared to no catheter placement in these veins (28.3% vs 28.6% and 35% vs 26.7% respectively; p >0.1). However, CVS was significantly more common in patients with previous/ current subclavian vein catheterization compared to no catheter placement in this vein (47.8% vs 22.9%, p = 0.02). CVS is highly prevalent among studied HD patients, particularly in the presence of suggestive clinical signs. The number of HD catheter placements and subclavian vein utilization for dialysis access impose a significantly higher risk of CVS.

Introduction Racial disparities in obesity exist at the individual and community levels. Retail food environment has been hypothesized to be associated with racial disparities in obesity prevalence. This study aimed to quantify how much food environment measures explain racial disparities in obesity at the county level. Methods Data from 2009 to 2010 on 3,135 U.S. counties were extracted from the U.S. Department of Agriculture Food Environment Atlas and the Behavioral Risk Factor Surveillance System and analyzed in 2013. Oaxaca–Blinder decomposition was used to quantify the portion of the gap in adult obesity prevalence observed between counties with a high and low proportion of African American residents is explained by food environment measures (e.g., proximity to grocery stores, per capita fast food restaurants). Counties were considered to have a high African American population if the percentage of African American residents was >13.1%, which represents the 2010 U.S. Census national estimate of percentage African American citizens. Results There were 665 counties (21%) classified as a high African American county. The total gap in mean adult obesity prevalence between high and low African American counties was found to be 3.35 percentage points (32.98% vs 29.63%). Retail food environment measures explained 13.81% of the gap in mean age-adjusted adult obesity prevalence. Conclusions Retail food environment explains a proportion of the gap in adult obesity prevalence observed between counties with a high proportion of African American residents and counties with a low proportion of African American residents.

Most patients with type 2 diabetes mellitus (T2DM) have at least one comorbid chronic disease. These comorbidities increase disease burden and costs and may impact the selection of glucose-lowering therapies. The aim of our study was to describe the prevalence and co-prevalence of comorbidities in patients with T2DM in Belgium. This was a single centre, transversal, descriptive study performed at Saint-Luc University Hospital, Brussels, Belgium. T2DM patients aged >18 years presenting to the outpatient diabetes clinic and regularly followed (≥1 year) between July 2011 and 2016 were included in the database. Information on descriptive characteristics was collected and several comorbidities were assessed. Overall, 778 patients were included. The median age was 68 years. The most frequently observed comorbidities were hypertension (85.5%), metabolic syndrome (MetS; 84.6%) and non-alcoholic hepatic steatosis (71.7%). 78.5% of the T2DM patients had ≥4 comorbidities. The highest co-prevalence of comorbidities was the combination of MetS and hypertension (75.8%), MetS and overweight (60.5%), and hypertension and overweight (56.6%). The observed prevalence and co-prevalence of comorbidities in T2DM Belgian patients was high, with 95.0% patients having at least two comorbid conditions.

Full Text Available Abstract Background It is well known that the prevalence of asthma has been reported to increase in many places around the world during the last decades. Therefore, the aim of this study was to identify and review studies of asthma prevalence among children in China and address time trends and regional variation in asthma. Methods A systematic literature search was performed using PubMed and China National Knowledge Infrastructure (CNKI databases. Selected articles had to describe an original study that showed the prevalence of asthma among children aged 0−14 years. Results A total of 74 articles met the inclusion criteria. The lifetime prevalence of asthma varied between 1.1% in Lhasa (Tibet and 11.0% in Hong Kong in studies following the International Study of Asthma and Allergies in Childhood (ISAAC protocol. The prevalence was 3% or lower in most articles following Chinese diagnostic criteria. One article reported the results from two national surveys and showed that the current average prevalence of asthma for the total study population had increased from 1990 to 2000 (0.9% to 1.5%. The lowest current prevalence was found in Lhasa (0.1% in 1990, 0.5% in 2000. Conclusions The prevalence of childhood asthma was generally low, both in studies following the ISAAC and Chinese diagnostic criteria. Assessment of time trends and regional variations in asthma prevalence was difficult due to insufficient data, variation in diagnostic criteria, difference in data collection methods, and uncertainty in prevalence measures. However, the findings from one large study of children from 27 different cities support an increase in current prevalence of childhood asthma from 1990 to 2000. The lowest current prevalence of childhood asthma was found in Tibet.

Work as a librarian involves exposure to potential risk factors for developing upper limb disorders. The prevalence of upper limb symptoms has, however, not previously been assessed in this occupational group. To estimate the 7-day and annual prevalence of self-reported neck and upper limb symptoms in librarians and to examine associations with specific tasks and ergonomic risk factors. A cross-sectional study using components of the standardized Nordic questionnaire. The study population consisted of librarians employed by a large local authority, and data collection was by means of a self-administered questionnaire. from studies on keyboard workers and on the general population were used as comparators. The 7-day prevalence of self-reported neck and upper limb pain in female librarians was 42% (95% confidence interval (CI) 33.7-50.5) and the annual prevalence was 65% (95% CI 56.6-72.8). The prevalence of reported wrist and hand pain increased with increased working involving a wide thumb-index span (P librarians was high, but there was insufficient evidence to confirm whether the prevalence was higher than in the general population or among keyboard workers. Working with a wide thumb-index span was associated with reporting upper limb symptoms.

To analyze the existing variability on molar incisor hypomineralization prevalence in the literature; to distinguish the various molar incisor hypomineralization prevalence rates in different countries, areas, and regions of the world; and to know the valid diagnostic criteria used for the correct identification of molar incisor hypomineralization prevalence. A literature review from Medline and Cochrane Library online databases was performed using five terms individually or in combination. Articles not reporting diagnostic criteria employed and articles not written English were excluded. The results were analyzed by country, region, year of study, sample size, range of age, and prevalence rate. A total of 37 articles in English were selected from 1987 to 2014 and from those only 14 employed the EAPD's 2003 diagnostic criteria. The reported age range varied from 5.5 to 17 years; the most frequently range used was 7 to 9 years. A wide prevalence range from 2.8% to 44% was found and 82.61% of the articles reported calibrated examiners. Comparison among the results of the studies is difficult due to the use of different indexes and diagnostic criteria, the analysis variability, selection methods, and different age groups. In reality, we are probably far from knowing the real MIH prevalence.

Autosomal dominant polycystic kidney disease (ADPKD) is a leading cause of end-stage renal disease, but estimates of its prevalence vary by >10-fold. The objective of this study was to examine the public health impact of ADPKD in the European Union (EU) by estimating minimum prevalence (point prevalence of known cases) and screening prevalence (minimum prevalence plus cases expected after population-based screening). A review of the epidemiology literature from January 1980 to February 2015 identified population-based studies that met criteria for methodological quality. These examined large German and British populations, providing direct estimates of minimum prevalence and screening prevalence. In a second approach, patients from the 2012 European Renal Association‒European Dialysis and Transplant Association (ERA-EDTA) Registry and literature-based inflation factors that adjust for disease severity and screening yield were used to estimate prevalence across 19 EU countries (N = 407 million). Population-based studies yielded minimum prevalences of 2.41 and 3.89/10 000, respectively, and corresponding estimates of screening prevalences of 3.3 and 4.6/10 000. A close correspondence existed between estimates in countries where both direct and registry-derived methods were compared, which supports the validity of the registry-based approach. Using the registry-derived method, the minimum prevalence was 3.29/10 000 (95% confidence interval 3.27-3.30), and if ADPKD screening was implemented in all countries, the expected prevalence was 3.96/10 000 (3.94-3.98). ERA-EDTA-based prevalence estimates and application of a uniform definition of prevalence to population-based studies consistently indicate that the ADPKD point prevalence is <5/10 000, the threshold for rare disease in the EU. © The Author 2016.

Periodontitis and type 2 diabetes mellitus are known to be associated. The relationship between periodontal microbiota and early diabetes risk has not been studied. We investigated the association between periodontal bacteria and prediabetes prevalence among diabetes-free adults. ORIGINS (the Oral Infections, Glucose Intolerance and Insulin Resistance Study) cross sectionally enrolled 300 diabetes-free adults aged 20 to 55 y (mean ± SD, 34 ± 10 y; 77% female). Prediabetes was defined as follows: 1) hemoglobin A1c values ranging from 5.7% to 6.4% or 2) fasting plasma glucose ranging from 100 to 125 mg/dL. In 1,188 subgingival plaque samples, 11 bacterial species were assessed at baseline, including Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia, and Actinomyces naeslundii. Full-mouth clinical periodontal examinations were performed, and participants were defined as having no/mild periodontitis vs. moderate/severe periodontitis per the definition of the Centers for Disease Control and Prevention / American Academy of Periodontology. Modified Poisson regression evaluated prediabetes prevalence across bacterial tertiles. Prevalence ratios and 95% confidence intervals for third vs. first tertiles are presented. All analyses were adjusted for cardiometabolic risk factors. All results presented currently arise from the baseline cross section. Prediabetes prevalence was 18%, and 58% of participants had moderate/severe periodontitis. Prevalence ratios (95% confidence intervals) summarizing associations between bacterial levels and prediabetes were as follows: A. actinomycetemcomitans, 2.48 (1.34, 4.58), P = 0.004; P. gingivalis, 3.41 (1.78, 6.58), P = 0.0003; T. denticola, 1.99 (0.992, 4.00), P = 0.052; T. forsythia, 1.95 (1.0, 3.84), P = 0.05; A. naeslundii, 0.46 (0.25, 0.85), P = 0.01. The prevalence ratio for prediabetes among participants with moderate/severe vs. no/mild periodontitis was 1.47 (0.78, 2.74), P

Full Text Available Mapping of Historic US Hookworm prevalence data from the Rockefeller Sanitary Commission (early 1900s using current GIS (Geographic Information System software (county shape files illustrates the extremely high prevalence of hookworm disease (Uncariasis in the Southeastern US at the time. Some counties in 7 states recorded 50% to 100% of the population with positive screens for hookworm in a monumental surveillance and treatment campaign. Narrative descriptions mentioned higher prevalence in “sand districts” vs. “clay districts”. In order to validate this description for historic data, further GIS databases (STATSGO were used to classify and quantify the % acreage in Eastern North Carolina falling into moderately- to well-drained soil types. These were then mapped and compared with the historic prevalence data. Most severely infested counties had at least 50% moderately to well-drained soil. Further analysis on soil data for other states with “coastal plains” could provide more background information on Environmental conditions for hookworm prevalence and distribution in US history. “Since history has no properly scientific value, its only purpose is educative. And if historians neglect to educate the public, if they fail to interest it intelligently in the past, then all their historical learning is valueless except in so far as it educates themselves”.

Background: Anecdotal evidence suggests that the sensitivity and specificity of a diagnostic test may vary with disease prevalence. Our objective was to investigate the associations between disease prevalence and test sensitivity and specificity using studies of diagnostic accuracy. Methods: We used data from 23 meta-analyses, each of which included 10–39 studies (416 total). The median prevalence per review ranged from 1% to 77%. We evaluated the effects of prevalence on sensitivity and specificity using a bivariate random-effects model for each meta-analysis, with prevalence as a covariate. We estimated the overall effect of prevalence by pooling the effects using the inverse variance method. Results: Within a given review, a change in prevalence from the lowest to highest value resulted in a corresponding change in sensitivity or specificity from 0 to 40 percentage points. This effect was statistically significant (p disease prevalence; there was no such systematic effect for sensitivity. Interpretation: The sensitivity and specificity of a test often vary with disease prevalence; this effect is likely to be the result of mechanisms, such as patient spectrum, that affect prevalence, sensitivity and specificity. Because it may be difficult to identify such mechanisms, clinicians should use prevalence as a guide when selecting studies that most closely match their situation. PMID:23798453

BACKGROUND Over the past 10 years, there has been a significant increase in the use of assisted reproductive technologies in Canada, however, little is known about the overall prevalence of infertility in the population. The purpose of the present study was to estimate the prevalence of current infertility in Canada according to three definitions of the risk of conception. METHODS Data from the infertility component of the 2009–2010 Canadian Community Health Survey were analyzed for married and common-law couples with a female partner aged 18–44. The three definitions of the risk of conception were derived sequentially starting with birth control use in the previous 12 months, adding reported sexual intercourse in the previous 12 months, then pregnancy intent. Prevalence and odds ratios of current infertility were estimated by selected characteristics. RESULTS Estimates of the prevalence of current infertility ranged from 11.5% (95% CI 10.2, 12.9) to 15.7% (95% CI 14.2, 17.4). Each estimate represented an increase in current infertility prevalence in Canada when compared with previous national estimates. Couples with lower parity (0 or 1 child) had significantly higher odds of experiencing current infertility when the female partner was aged 35–44 years versus 18–34 years. Lower odds of experiencing current infertility were observed for multiparous couples regardless of age group of the female partner, when compared with nulliparous couples. CONCLUSIONS The present study suggests that the prevalence of current infertility has increased since the last time it was measured in Canada, and is associated with the age of the female partner and parity.

One-year prevalence rates of alcohol abuse (2.3% vs. 3.9%; Z=-2.04; p<0.05 and dependence (2.7% vs. 8.2%; Z=-5.24; p<0.001 were less prevalent in the male prison population than in the general population. CONCLUSIONS: Service provision for prison populations in Chile should acknowledge high rates of depression and illicit drug use. Overall prevalence rates are lower than reported in other LMICs. Previous research in prison populations in LMICs might have overestimated prevalence rates of mental disorders.

Hypospadias is one of the most common congenital anomalies but the etiology is not fully understood. There seem to be genetic, endocrinological, and environmental factors involved. Great geographical variation in the prevalence of hypospadias has been reported both between and within countries. We studied the determinants of geographical variation in the prevalence of hypospadias in Finland. All patients treated for hypospadias in 1970-1996 before the age of 9 years among boys born in 1970-1986 were identified in the national hospital discharge registry. Prevalence of hypospadias was calculated for each of the 355 municipalities in Finland. Demographic data were obtained from Statistics Finland. Association of the explanatory factors with prevalence of hypospadias was assessed using Poisson regression methods. The prevalence of operated hypospadias varied between provinces and between university hospital districts, from a ratio of 0.65 to a ratio of 1.01. An association between the prevalence of hypospadias and the remoteness from the closest city was observed. There was no association with level of education, social class, or occupation. The observed differences in the prevalence of operated hypospadias in Finland may have several explanations. Different levels of ascertainment and both genetic and environmental factors can not be ruled out

Full Text Available Abstract Background In China, high prevalence of HBV and HCV parallels with the growing epidemic of syphilis and HIV in the general population poses a great threat to blood safety. This study investigated the prevalence of serologic markers for transfusion transmissible infections (TTIs among four Chinese blood centers. Methods We examined whole blood donations collected from January 2000 through December 2010 at four Chinese blood centers. Post-donation testing of TTIs (HIV, HBV, HCV and syphilis were conducted using two different enzyme-linked immunosorbent assay kits for each seromarker. The prevalence of serologic markers for TTIs (% was calculated and additional analysis was conducted to examine donor characteristics associated with positive TTIs serology. Results Of the 4,366,283 donations, 60% were from first-time donors and 40% were from repeated donors. The overall prevalence of HIV, HBsAg, HCV and syphilis was 0.08%, 0.86%, 0.51% and 0.47%, respectively. The prevalence profile of TTIs varied among different blood centers and appeared at relatively high levels. Overall, the prevalence of HBsAg and HCV demonstrated a decline trend among four blood centers, while the prevalence of HIV and syphilis displayed three different trends: constantly steady, continually increasing and declining among different centers. Conclusions This study reflects the risk of TTIs has been greatly reduced in China, but blood transfusion remains an ongoing risk factor for the spread of blood-borne infections, and further work and improvements are needed to strengthen both safety and availability of blood in China.

Full Text Available Aim. To evaluate the prevalence and possible etiological factors associated with molar incisor hypomineralization (MIH among a group of children in Jeddah, Saudi Arabia. Methods. A group of 8-12-year-old children were recruited (n=267  from the Pediatric Dental Clinics at the Faculty of Dentistry, King Abdulaziz University. Children had at least one first permanent molar (FPM, erupted or partially erupted. Demographic information, children’s medical history, and pregnancy-related data were obtained. The crowns of the FPM and permanent incisors were examined for demarcated opacities, posteruptive breakdown (PEB, atypical restorations, and extracted FPMs. Children were considered to have MIH if one or more FPM with or without involvement of incisors met the diagnostic criteria. Results. MIH showed a prevalence of 8.6%. Demarcated opacities were the most common form. Maxillary central incisors were more affected than mandibular (P=0.01. The condition was more prevalent in children with history of illnesses during the first four years of life including tonsillitis (P=0.001, adenoiditis (P=0.001, asthma (P=0.001, fever (P=0.014, and antibiotics intake (P=0.001. Conclusions. The prevalence of MIH is significantly associated with childhood illnesses during the first four years of life including asthma, adenoid infections, tonsillitis, fever, and antibiotics intake.

This study investigates the distribution pattern of asthma symptom prevalence in Latin American children aged 13-14 years. A randomized, cross-sectional and multicentric study on the prevalence and severity of asthma symptoms (lifetime asthma, current wheezing, and frequent sleep disturbance by wheezing) was conducted in 165,917 schoolchildren from 56 centers in 17 Latin American countries, as part of the International Study of Asthma and Allergies in Childhood (ISAAC), Phase Three. The prevalence of lifetime asthma prevalence ranged from 1.2% to 33.1%, whereas current wheezing went from 3.9% to 30.8% and frequent sleep disturbance from 0.6% to 6.1%. An important proportion of centers (55%) reported a prevalence of asthma symptoms over 15%. There was no significant correlation between asthma symptom prevalence and latitude, altitude, or tropical setting. At country level, the prevalence of asthma was not associated with gross national income (GNI), proportion of population under the poverty line, or ancestry. This study suggests that ecological interactions, probably typical for each locality, may be the main determinants for the large variability of asthma prevalence in Latin America. The high prevalence of asthma symptoms found in children living in areas with low socioeconomic development would challenge the protective role against asthma of factors related to low hygiene and poverty; contrarily, in this region they would act as risk factors.

In Latin America and the Caribbean, anemia has been a public health problem that affects mainly women of childbearing age and children under 6 years of age. However, the current prevalence of anemia in this region is unknown. To examine the latest available prevalence data on anemia in Latin America and the Caribbean. A systematic review was conducted in 2011 and updated in 2014. Studies determining the prevalence of anemia conducted in apparently healthy populations with national or regional representativeness were included in the review. The lowest prevalence rates of anemia among children under 6 years of age were found in Chile (4.0%), Costa Rica (4.0%), Argentina (7.6%), and Mexico (19.9%). In Nicaragua, Brazil, Ecuador, El Panama, and Honduras, anemia was a moderate public health problem, with prevalence ranging Salvador, Cuba, Colombia, the Dominican Republic, Peru, from 20.1% to 37.3%. Anemia was a severe public health problem in Guatemala, Haiti, and Bolivia. The prevalence of anemia among women of childbearing age was lowest in Chile (5.1%). In Colombia, El Salvador, Costa Rica, Nicaragua, Ecuador, Mexico, Peru, Honduras, and Argentina, anemia was a mild public health problem, with prevalence ranging from 7.6% to 18.7%. In Guatemala, Brazil, the Dominican Republic, and Bolivia, anemia was a moderate public health problem, with prevalence ranging from 21.4% to 38.3%. Panama and Haiti had the highest reported prevalence rates (40.0% and 45.5%, respectively), and anemia was considered a severe public health problem in those countries. Anemia remains a public health problem in children under 6 years of age and women of childbearing age in most Latin America and Caribbean countries for which data are available.

HIV prevalence varies from 1.7% to 14.8% between ethnic groups in Uganda. Understanding the factors responsible for this heterogeneity in HIV spread may guide prevention efforts. We evaluated the relationship between HIV prevalence by ethnic group and a range of risk factors as well as the prevalence of herpes simplex virus-2 (HSV-2), syphilis and symptomatic STIs in the 2004/2005 Uganda HIV/AIDS Sero-Behavioural Survey-a two stage, nationally representative, population based survey of 15-59-year-olds. Spearman's correlation was used to assess the relationship between HIV prevalence and each variable. There was a positive association between HIV prevalence and HSV-2, symptomatic STIs and high-risk sex (sex with a non-cohabiting, non-marital partner) for women. Non-significant positive associations were present between HIV and high-risk sex for men and lifetime number of partners for men and women. Variation in sexual behavior may contribute to the variations in HIV, HSV-2 and other STI prevalence by ethnic group in Uganda. Further work is necessary to delineate which combinations of risk factors determine differential STI spread in Uganda.

We report on the generation of non-separable beams produced via the interaction of a linearly polarized beam with a cloud of cold caesium atoms placed in an optical cavity. We convert the squeezing of the two linear polarization modes into quadrature entanglement and show how to find the best entanglement generated in a two-mode system using the inseparability criterion for continuous variables (Duan et al 2000 Phys. Rev. Lett. 84 2722). We verify this method experimentally with a direct measurement of the inseparability using two homodyne detectors. We then map this entanglement into a polarization basis and achieve polarization entanglement

Hereditary hemochromatosis is an autosomal recessive disorder associated with the HFE genes. Early identification and diagnosis is important as end stage organ damage may occur if treatment is delayed.. This study aimed to identify the prevalence of hereditary hemochromatosis in Kayseri and surroundings known as Central Anatolia. 2304 participants (1220 males, 1084 females) who were older then the age of 17 were included in the study conducted between December 2005 and December 2006 in Kayseri, Turkey. Transferin saturation was measured from overnight fasting blood samples. Serum iron, total iron binding capacity, and transferin saturation were measured. Serum ferritin levels and hereditary hemochromatosis genetic analysis were also performed after an overnight fasting blood samples from participants whose transferin saturation results were more than 50% in man and more than 45% in women. The homozygote C282Y mutation and heterozygote C282Y mutation prevalences were found as 0.08% (1/1220) and 0.08% (1/1220) in male participants, respectively. The heterozygote H63D mutation prevalence was found in 0.09% (1/1084) of female participants. Calculated prevalences in general population are as follows; The homozygote C282Y mutation prevalence is 0.043% (1/2304), the heterozygote C282Y mutation prevalence is 0.043% (1/2304) and the heterozygote H63D mutation prevalence is 0.043% (1/2304). The prevalence of hereditary hemochromatosis in Central Anatolia is 0.043% (1/2304). Because of the relatively low frequency, population screening studies are not cost-effective.

The goal was to determine the prevalence of high-risk HPV16 using saliva in a screening population in Detroit, Michigan. Real-time quantitative polymerase chain reaction was applied to detect HPV16 in saliva DNA from 349 screening subjects without head and neck cancer (HNC), 156 with HNC, and 19 controls. Cut points for human papilloma virus (HPV) positivity were >0 and >0.001 copy/cell. Proportions were compared between groups using exact χ(2) or Fisher exact tests (P 0, each group had an overall HPV prevalence of more than 5%, with a higher prevalence of 30.8% in the HNC patient group. At a cut point >0.001, the prevalence was lower: 0% in the control, 1.2% in the screening, and 16.7% in the HNC group. In the latter, for both cut points, HPV prevalence was different across sites (0, women in the screening group had a higher prevalence of HPV than did men (P = .010), and at >0.001, the prevalence was higher for men in the HNC group than for women (P = .035). In the screening group, at >0, only African Americans had a higher prevalence than Caucasian Americans (P = .025). In the screening group, a 6.9% and 1.2% screening rate was noted at cut points >0 and >0.001, respectively. The results provide data to inform public health considerations of the feasibility of saliva as a screening tool in at-risk populations with the long-term goal of prophylactic vaccination against oral HPV.

About 1 million people worldwide commit suicide each year, and college students with suicidal ideation are at high risk of suicide. The prevalence of suicidal ideation in college students has been estimated extensively, but quantitative syntheses of overall prevalence are scarce, especially in China. Accurate estimates of prevalence are important for making public policy. In this paper, we aimed to determine the prevalence of suicidal ideation in Chinese college students. Databases including PubMed, Web of Knowledge, Chinese Web of Knowledge, Wangfang (Chinese database) and Weipu (Chinese database) were systematically reviewed to identify articles published between 2004 to July 2013, in either English or Chinese, reporting prevalence estimates of suicidal ideation among Chinese college students. The strategy also included a secondary search of reference lists of records retrieved from databases. Then the prevalence estimates were summarized using a random effects model. The effects of moderator variables on the prevalence estimates were assessed using a meta-regression model. A total of 41 studies involving 160339 college students were identified, and the prevalence ranged from 1.24% to 26.00%. The overall pooled prevalence of suicidal ideation among Chinese college students was 10.72% (95%CI: 8.41% to 13.28%). We noted substantial heterogeneity in prevalence estimates. Subgroup analyses showed that prevalence of suicidal ideation in females is higher than in males. The prevalence of suicidal ideation in Chinese college students is relatively high, although the suicide rate is lower compared with the entire society, suggesting the need for local surveys to inform the development of health services for college students.

We aimed to estimate the prevalence of refractory hypertension (RfH) and to determine the clinical differences between these patients and resistant hypertensives (RH). Secondly, we assessed the prevalence of white-coat RfH and clinical differences between true- and white-coat RfH patients. The present analysis was conducted on the Spanish Ambulatory Blood Pressure Monitoring Registry database containing 70 997 treated hypertensive patients. RH and RfH were defined by the presence of elevated office blood pressure (≥140 and/or 90 mm Hg) in patients treated with at least 3 (RH) and 5 (RfH) antihypertensive drugs. White-coat RfH was defined by RfH with normal (<130/80 mm Hg) 24-hour blood pressure. A total of 11.972 (16.9%) patients fulfilled the standard criteria of RH, and 955 (1.4%) were considered as having RfH. Compared with RH patients, those with RfH were younger, more frequently male, and after adjusting for age and sex, had increased prevalence of target organ damage, and previous cardiovascular disease. The prevalence of white coat RfH was lower than white-coat RH (26.7% versus 37.1%, P <0.001). White-coat RfH, in comparison with those with true RfH, showed a lower prevalence of both left ventricular hypertrophy (22% versus 29.7%; P =0.018) and microalbuminuria (28.3% versus 42.9%; P =0.047). The prevalence of RfH was low and these patients had a greater cardiovascular risk profile compared with RH. One out of 4 patients with RfH have normal 24-hour blood pressure and less target organ damage, thus indicating the important role of ambulatory blood pressure monitoring in guiding antihypertensive therapy in difficult-to-treat patients. © 2017 The Authors.

To describe prevalence of anisometropia, defined in terms of both sphere and cylinder, examined cross-sectionally, in school-aged members of a Native American tribe with a high prevalence of astigmatism. Cycloplegic autorefraction measurements, confirmed by retinoscopy and, when possible, by subjective refraction were obtained from 1041 Tohono O'odham children, 4 to 13 years of age. Astigmatism > or =1.00 diopter (D) was present in one or both eyes of 462 children (44.4%). Anisometropia > or =1.00 D spherical equivalent (SE) was found in 70 children (6.7%), and anisometropia > or =1.00 D cylinder was found in 156 children (15.0%). Prevalence of anisometropia did not vary significantly with age or gender. Overall prevalence of significant anisometropia was 18.1% for a difference between eyes > or =1.00 D SE or cylinder. Vector analysis of between-eye differences showed a prevalence of significant anisometropia of 25.3% for one type of vector notation (difference between eyes > or =1.00 D for M and/or > or =0.50 D for J0 or J45), and 16.2% for a second type of vector notation (between-eye vector dioptric difference > or =1.41). Prevalence of SE anisometropia is similar to that reported for other school-aged populations. However, prevalence of astigmatic anisometropia is higher than that reported for other school-aged populations.

Socioeconomic inequalities in health have been shown to vary for different diseases and by gender. This study aimed to examine gender differences in associations between asthma and socioeconomic disadvantage. Socioeconomic variables were assessed among men and women in the North West Adelaide Health Study, a representative population cohort (n = 4060) aged 18 years and over in metropolitan South Australia. Asthma was determined from spirometry and self-reported doctor diagnosis. The prevalence of asthma was 12.0% (95% CI: 11.1-13.1), and was significantly higher among women (13.5%) than men (10.5%). For participants aged 18-64 years a higher prevalence of asthma was associated with an education level of secondary school or lower, or not being in the paid labour force among men, and with a gross annual household income of $20,000 or less among women. Among socioeconomically advantaged groups, the prevalence of asthma was significantly higher among women than men. Socioeconomic disadvantage was associated with higher asthma prevalence, although this varied by gender depending on the indicator of socioeconomic position used. Men with low education or those not employed in the paid labour force had higher asthma prevalence than more socioeconomically advantaged men. Women with low income had higher asthma prevalence than those with higher income. Among all socioeconomically advantaged groups, and also the low-income group, women experienced a higher prevalence of asthma than men.

Giardia has a wide range of host species and is a common cause of diarrhoeal disease in humans and animals. Companion animals are able to transmit a range of zoonotic diseases to their owners including giardiasis, but the size of this risk is not well known. The aim of this study was to analyse giardiasis prevalence rates in dogs and cats worldwide using a systematic search approach. Meta-analysis enabled to describe associations between Giardia prevalence and various confounding factors. Pooled prevalence rates were 15.2% (95% CI 13.8-16.7%) for dogs and 12% (95% CI 9.2-15.3%) for cats. However, there was very high heterogeneity between studies. Meta-regression showed that the diagnostic method used had a major impact on reported prevalence with studies using ELISA, IFA and PCR reporting prevalence rates between 2.6 and 3.7 times greater than studies using microscopy. Conditional negative binomial regression found that symptomatic animals had higher prevalence rates ratios (PRR) than asymptomatic animals 1.61 (95% CI 1.33-1.94) in dogs and 1.94 (95% CI 1.47-2.56) in cats. Giardia was much more prevalent in young animals. For cats >6 months, PRR=0.47 (0.42-0.53) and in dogs of the same age group PRR=0.36 (0.32-0.41). Additionally, dogs kept as pets were less likely to be positive (PRR=0.56 (0.41-0.77)) but any difference in cats was not significant. Faecal excretion of Giardia is common in dogs and slightly less so in cats. However, the exact rates depend on the diagnostic method used, the age and origin of the animal. What risk such endemic colonisation poses to human health is still unclear as it will depend not only on prevalence rates but also on what assemblages are excreted and how people interact with their pets.

Kenyon, Chris Richard; Tsoumanis, Achilleas

2016-01-01

Background. Syphilis is curable but Herpes Simplex Virus-2 (HSV-2) is not. As a result, the prevalence of syphilis but not HSV-2 may be influenced by the efficacy of national STI screening and treatment capacity. If the prevalence of syphilis and HSV-2 is found to be correlated, then this makes it more likely that something other than differential STI treatment is responsible for variations in the prevalence of both HSV-2 and syphilis. Methods. Simple linear regression was used to evaluate the relationship between national antenatal syphilis prevalence and HSV-2 prevalence in women in two time periods: 1990–1999 and 2008. Adjustments were performed for the laboratory syphilis testing algorithm used and the prevalence of circumcision. Results. The prevalence of syphilis was positively correlated with that of HSV-2 for both time periods (adjusted correlations, 20–24-year-olds: 1990–99: R 2 = 0.54, P < 0.001; 2008: R 2 = 0.41, P < 0.001 and 40–44-year-olds: 1990–99: R 2 = 0.42, P < 0.001; 2008: R 2 = 0.49, P < 0.001). Conclusion. The prevalence of syphilis and HSV-2 is positively correlated. This could be due to a common set of risk factors underpinning both STIs. PMID:27069710

Goran, Michael I; Ulijaszek, Stanley J; Ventura, Emily E

2013-01-01

The overall aim of this study was to evaluate, from a global and ecological perspective, the relationships between availability of high fructose corn syrup (HFCS) and prevalence of type 2 diabetes. Using published resources, country-level estimates (n =43 countries) were obtained for: total sugar, HFCS and total calorie availability, obesity, two separate prevalence estimates for diabetes, prevalence estimate for impaired glucose tolerance and fasting plasma glucose. Pearson's correlations and partial correlations were conducted in order to explore associations between dietary availability and obesity and diabetes prevalence. Diabetes prevalence was 20% higher in countries with higher availability of HFCS compared to countries with low availability, and these differences were retained or strengthened after adjusting for country-level estimates of body mass index (BMI), population and gross domestic product (adjusted diabetes prevalence=8.0 vs. 6.7%, p=0.03; fasting plasma glucose=5.34 vs. 5.22 mmol/L, p=0.03) despite similarities in obesity and total sugar and calorie availability. These results suggest that countries with higher availability of HFCS have a higher prevalence of type 2 diabetes independent of obesity.

Finding the faithless: perceived atheist prevalence reduces anti-atheist prejudice.

Science.gov (United States)

Gervais, Will M

2011-04-01

Although prejudice is typically positively related to relative outgroup size, four studies found converging evidence that perceived atheist prevalence reduces anti-atheist prejudice. Study 1 demonstrated that anti-atheist prejudice among religious believers is reduced in countries in which atheists are especially prevalent. Study 2 demonstrated that perceived atheist prevalence is negatively associated with anti-atheist prejudice. Study 3 demonstrated a causal relationship: Reminders of atheist prevalence reduced explicit distrust of atheists. These results appeared distinct from intergroup contact effects. Study 4 demonstrated that prevalence information decreased implicit atheist distrust. The latter two experiments provide the first evidence that mere prevalence information can reduce prejudice against any outgroup. These findings offer insights about anti-atheist prejudice, a poorly understood phenomenon. Furthermore, they suggest both novel directions for future prejudice research and potential interventions that could reduce a variety of prejudices.

Central nervous system dysfunction, such as hyperexcitation, irritability, and disturbance of consciousness, may occur in patients with thyrotoxicosis. There are also a few case reports of seizures attributed to thyrotoxicosis. The objective of the present study was to determine the prevalence of seizures that appeared to be related to the thyrotoxic state in patients with thyrotoxicosis. We retrospectively determined the prevalence and clinical features of seizures in 3382 patients with hyperthyroidism. Among patients with seizures, we excluded those with other causes of seizures or a history of epilepsy. We did not exclude two patients in whom later work-up showed an abnormal magnetic resonance imaging, as their seizures resolved after they became euthyroid. Among the 3382 patients with hyperthyroidism, there were seven patients (0.2%) with seizures who met our criteria. Primary generalized tonic-clonic seizures occurred in four patients (57%), complex partial seizures with secondary generalized tonic-clonic seizures occurred in two patients (29%), and one patient had a focal seizure (14%). The initial electroencephalography (EEG) was normal in two patients (29%), had generalized slow activity in four patients (57%), and had diffuse generalized beta activity in one patient (14%). On magnetic resonance imaging, one patient had diffuse brain atrophy, and one had an old basal ganglia infarct. After the patients became euthyroid, the EEG was repeated and was normal in all patients. During follow-up periods ranging from 18 to 24 months, none of the patients had seizures. Hyperthyroidism is the precipitating cause of seizures in a small percentage of these patients. In these patients, the prognosis is good if they become euthyroid. The prevalence of thyrotoxicosis-related seizures reported here can be used in conjunction with the prevalence of thyrotoxicosis in the population to estimate the prevalence of thyrotoxicosis-related seizures in populations.

Maps of malaria distribution are vital for optimal allocation of resources for anti-malarial activities. There is a lack of reliable contemporary malaria maps in endemic countries in sub-Saharan Africa. This problem is particularly acute in low malaria transmission countries such as those located in the horn of Africa. Data from a national malaria cluster sample survey in 2005 and routine cluster surveys in 2007 were assembled for Somalia. Rapid diagnostic tests were used to examine the presence of Plasmodium falciparum parasites in finger-prick blood samples obtained from individuals across all age-groups. Bayesian geostatistical models, with environmental and survey covariates, were used to predict continuous maps of malaria prevalence across Somalia and to define the uncertainty associated with the predictions. For analyses the country was divided into north and south. In the north, the month of survey, distance to water, precipitation and temperature had no significant association with P. falciparum prevalence when spatial correlation was taken into account. In contrast, all the covariates, except distance to water, were significantly associated with parasite prevalence in the south. The inclusion of covariates improved model fit for the south but not for the north. Model precision was highest in the south. The majority of the country had a predicted prevalence of or = 5% prevalence were predominantly in the south. The maps showed that malaria transmission in Somalia varied from hypo- to meso-endemic. However, even after including the selected covariates in the model, there still remained a considerable amount of unexplained spatial variation in parasite prevalence, indicating effects of other factors not captured in the study. Nonetheless the maps presented here provide the best contemporary information on malaria prevalence in Somalia.

Prevalence of suicidal ideation in Chinese college students: a meta-analysis.

Zhan-Zhan Li

Full Text Available BACKGROUND: About 1 million people worldwide commit suicide each year, and college students with suicidal ideation are at high risk of suicide. The prevalence of suicidal ideation in college students has been estimated extensively, but quantitative syntheses of overall prevalence are scarce, especially in China. Accurate estimates of prevalence are important for making public policy. In this paper, we aimed to determine the prevalence of suicidal ideation in Chinese college students. OBJECTIVE AND METHODS: Databases including PubMed, Web of Knowledge, Chinese Web of Knowledge, Wangfang (Chinese database and Weipu (Chinese database were systematically reviewed to identify articles published between 2004 to July 2013, in either English or Chinese, reporting prevalence estimates of suicidal ideation among Chinese college students. The strategy also included a secondary search of reference lists of records retrieved from databases. Then the prevalence estimates were summarized using a random effects model. The effects of moderator variables on the prevalence estimates were assessed using a meta-regression model. RESULTS: A total of 41 studies involving 160339 college students were identified, and the prevalence ranged from 1.24% to 26.00%. The overall pooled prevalence of suicidal ideation among Chinese college students was 10.72% (95%CI: 8.41% to 13.28%. We noted substantial heterogeneity in prevalence estimates. Subgroup analyses showed that prevalence of suicidal ideation in females is higher than in males. CONCLUSIONS: The prevalence of suicidal ideation in Chinese college students is relatively high, although the suicide rate is lower compared with the entire society, suggesting the need for local surveys to inform the development of health services for college students.

Full Text Available Congenital malformation (CM will begin to emerge as one of the major childhood health problems .Treatment and rehabilitation of children with congenital malformations are costly and complete recovery is usually impossible. The aim of this study was to determine frequency of CM in Yazd central city of the Islamic Republic of Iran to find out if there has been any difference in the rate and types of CM in this area. This descriptive-observational study carried on 4800 births delivered at all maternity hospitals in Yazd from October 2003 to June 2004. Prevalence of CM was 2.83% (2.86 % in male and 2.68 % in female out of the 136 cases 69(51.88% were males and 64 (48.12% were females and 3 with ambiguous genitalia. Positive family history of CM in sibling was in only 6 cases (4.41%.Overall, musculoskeletal (0.83%, central nerv-ous system (0.47% and genital system (0.37% were accounted as the most common. Frequency of CM was more seen in still birth (12.5% as in comparison to live birth (2.71%. There was not statistical difference be-tween prevalence of CM and neonatal's gender, gestational age, birth order and mother's age, drug ingestion, illness and parental consanguinity. In this study the overall prevalence of congenital malformation among the newborn was higher than those previous reported in Iran and determining the causes of this difference needs more extensive studies.

Condoning stereotyping? How awareness of stereotyping prevalence impacts expression of stereotypes.

Science.gov (United States)

Duguid, Michelle M; Thomas-Hunt, Melissa C

2015-03-01

The deleterious effects of stereotyping on individual and group outcomes have prompted a search for solutions. One approach has been to increase awareness of the prevalence of stereotyping in the hope of motivating individuals to resist natural inclinations. However, it could be that this strategy creates a norm for stereotyping, which paradoxically undermines desired effects. The present research demonstrates that individuals who received a high prevalence of stereotyping message expressed more stereotypes than those who received a low prevalence of stereotyping message (Studies 1a, 1b, 1c, and 2) or no message (Study 2). Furthermore, working professionals who received a high prevalence of stereotyping message were less willing to work with an individual who violated stereotypical norms than those who received no message, a low prevalence of stereotyping message, or a high prevalence of counter-stereotyping effort message (Study 3). Also, in a competitive task, individuals who received a high prevalence of stereotyping message treated their opponents in more stereotype-consistent ways than those who received a low prevalence of stereotyping message or those who received a high prevalence of counter-stereotyping effort message (Study 4).

Scabies is a skin disease that, through secondary bacterial skin infection (impetigo), can lead to serious complications such as septicaemia, renal disease, and rheumatic heart disease. Yet the worldwide prevalence of scabies is uncertain. We undertook a systematic review, searching several databases and the grey literature, for population-based studies that reported on the prevalence of scabies and impetigo in a community setting. All included studies were assessed for quality. 2409 articles were identified and 48 studies were included. Data were available for all regions except North America. The prevalence of scabies ranged from 0·2% to 71·4%. All regions except for Europe and the Middle East included populations with a prevalence greater than 10%. Overall, scabies prevalence was highest in the Pacific and Latin American regions, and was substantially higher in children than in adolescents and adults. Impetigo was common, particularly in children, with the highest prevalence in Australian Aboriginal communities (49·0%). Comprehensive scabies control strategies are urgently needed, such as a community-based mass drug administration approach, along with a more systematic approach to the monitoring of disease burden.

One of the most prevalent chronic diseases among elderly population is the Metabolic Syndrome (MetS). The aim of this study was to assess the prevalence of MetS and associated factors among Mexican elderly people. Cross-sectional survey carried out in Mexico (2007). A random sample (n=516) of the elderly population (≥65years; 277 female, 239 male) was interviewed. Anthropometric and analytical measurements, and a general questionnaire incorporating questions related to socio-demographic and life-style factors were used. MetS definition AHA/NHLBI/IDF was applied. The prevalence of MetS in the elderly (≥65years) was of 72.9% (75.7% men; 70.4% women). Participants with values above MetS cut-off points were 92.4% (hypertension), 77.8% (hypertriglyceridemia), 77.1% (low HDL-cholesterol), 71.1% (hyperglycaemia), and 65.4% (central obesity). People with MetS showed higher values of anthropometric and biochemical variables than those without MetS, except for the height, cholesterol and creatinine. Mid-high education level (9-12 years), no smokers and former smokers, and Central-Western inhabitants of Mexico were associated with MetS components. BMI status was the main determinant of MetS prevalence and MetS components. The reported prevalence of MetS among the elderly Mexican population was higher than those previously obtained in the geographical area, showing a major public health problem in Mexican elders.

To evaluate the published medical literature on the prevalence and types of food allergies in South Asia. A PubMed search was performed using the keywords India and food allergy, Asia and food allergy, and South Asia and food allergy for any period. Articles cited in selected studies were reviewed for their appropriateness of inclusion into this review. Publications were included that were original research and fit the topic of food allergy and South Asia. South Asia is defined as region inclusive of India, Pakistan, Bangladesh, and Sri Lanka. A total of 169 articles were initially identified, and 47 were reviewed in detail for inclusion in this review. The primary focus was placed on 10 studies that consisted of case reports of newly reported or documented food allergy, survey studies that investigated food allergy prevalence in specific demographics, and prospective and cross-sectional studies with case controls, all of which investigated food allergy prevalence by allergy testing in a selected population. The medical literature on the prevalence and types of food allergy in South Asia indicates that there is a variety of unusual and unique allergens and an overall low incidence of food allergy. There is also an association of increased food allergy prevalence in individuals who live in metropolitan regions or who migrate to communities that have adopted westernization.

Diabetes is an important contributor to global morbidity and mortality. The contributions of population aging and macroeconomic changes to the growth in diabetes prevalence over the past 20 years are unclear. We used cross-sectional data on age- and sex-specific counts of people with diabetes by country, national population estimates, and country-specific macroeconomic variables for the years 1990, 2000, and 2008. Decomposition analysis was performed to quantify the contribution of population aging to the change in global diabetes prevalence between 1990 and 2008. Next, age-standardization was used to estimate the contribution of age composition to differences in diabetes prevalence between high-income (HIC) and low-to-middle-income countries (LMICs). Finally, we used non-parametric correlation and multivariate first-difference regression estimates to examine the relationship between macroeconomic changes and the change in diabetes prevalence between 1990 and 2008. Globally, diabetes prevalence grew by two percentage points between 1990 (7.4 %) and 2008 (9.4 %). Population aging was responsible for 19 % of the growth, with 81 % attributable to increases in the age-specific prevalences. In both LMICs and HICs, about half the growth in age-specific prevalences was from increasing levels of diabetes between ages 45-65 (51 % in HICs and 46 % in LMICs). After age-standardization, the difference in the prevalence of diabetes between LMICs and HICs was larger (1.9 % point difference in 1990; 1.5 % point difference in 2008). We found no evidence that macroeconomic changes were associated with the growth in diabetes prevalence. Population aging explains a minority of the recent growth in global diabetes prevalence. The increase in global diabetes between 1990 and 2008 was primarily due to an increase in the prevalence of diabetes at ages 45-65. We do not find evidence that basic indicators of economic growth, development, globalization, or urbanization were related

2017-03-01

Full Text Available PURPOSE: Many studies have investigated the prevalence of neck pain (NP and its risk factors in general population. However, the prevalence of NP among athletes has not been systematically investigated yet. We aimed to systematically review the NP prevalence in athletes. As respects of various definitions of NP, response rates and reliability of studies instruments, we considered risk of bias for including studies. METHODS: A comprehensive search was conducted in Sep 2015, using PubMed, Ovid SP Medline, ISI and Google Scholar. We included studies in English that reported the prevalence of NP in an athletic population in a specifically defined period of time. Two reviewers independently assessed the studies' quality, and performed data extractions. RESULTS: Of 1675 titles identified, 8 articles were assessed for bias risk and 6 with low and moderate risk were included. NP was shown to be prevalent in athletes with a oneweek prevalence ranging from 8% to 45%, a one-year prevalence ranging from 38% to 73% and life-time prevalence about 48%. CONCLUSION: Similar to general population, the prevalence of NP in the athletes is high. Therefore, more studies regarding pain prevalences and risk factors may be useful for planning the educational programs, appropriate rehabilitation protocols, and development of preventive guidelines. Researchers are encouraged to perform epidemiologic studies with low risk of bias in this regard.

Type 2 diabetes mellitus (T2DM) incidence is traditionally derived from cohort studies that are not always feasible, representative, or available. The present study estimates T2DM incidence in Fijian adults from T2DM prevalence estimates assembled from surveys of 25-64 year old adults conducted over 30 years (n = 14,288). T2DM prevalence by five-year age group from five population-based risk factor surveys conducted over 1980-2011 were variously adjusted for urban-rural residency, ethnicity, and sex to previous censuses (1976, 1986, 1996, 2009) to improve representativeness. Prevalence estimates were then used to calculate T2DM incidence based on birth cohorts from the age-period (Lexis) matrix following the Styblo technique, first used to estimate annual risk of tuberculosis infection (incidence) from sequential Mantoux population surveys. Poisson regression of year, age, sex, and ethnicity strata (n = 160) was used to develop projections of T2DM prevalence and incidence to 2020 based on various scenarios of population weight measured by body mass index (BMI) change. T2DM prevalence and annual incidence increased in Fiji over 1980-2011. Prevalence was higher in Indians and men than i-Taukei and women. Incidence was higher in Indians and women. From regression analyses, absolute reductions of 2.6 to 5.1% in T2DM prevalence (13-26% lower), and 0.5-0.9 per 1000 person-years in incidence (8-14% lower), could be expected in 2020 in adults if mean population weight could be reduced by 1-4 kg, compared to the current period trend in weight gain. This is the first application of the Styblo technique to calculate T2DM incidence from population-based prevalence surveys over time. Reductions in population BMI are predicted to reduce T2DM incidence and prevalence in Fiji among adults aged 25-64 years.

SELF-REALIZATION IS INSEPARABLE FROM SELF-ACTUALIZATION OF A PERSONALITY

Irina Ivanovna Vitkovskaya

2016-02-01

Full Text Available The article considers the issues of a personality’s self-realization and self-actualization under current educational standards required in the time of impetuous development in informative technologies. The practical aspect of the article describes self-realization and self-actualization of a person as their social and useful activity, interdiscipline approach, it is characterised by interdependence of an individual and their social environment apart with the self-realization of a personality in educational process. Evidently, being a substantial ca-tegory of vital «self-assertion», it should be thought over in categories of self-actualization and self-realization. So, self-realization is considered to be a social process which continues all conscientious life. In pedagogics of our country, labour and professional activity were the spheres of self-actualization therefore, it should be taken into account external factors for self-realization and self-actualization of a person. If socio-pedagogic conditions presuppose having good teachers, what conditions should be created in an individual’s micro-groups and in particular, in the family and kind of values shoud an individual get through the process of socialization. Thus, technological project of self-realization of a personality has to assume that there is the strive for self-perfection and interrelation of ways of self-realization, self-education, and adaptation. The correlation of these ways in a specific educational field is the purpose of the article.

To describe the prevalence of high astigmatism in infants and young children who are members of a Native American tribe with a high prevalence of astigmatism. SureSight autorefraction measurements were obtained for 1461 Tohono O'odham children aged 6 months to 8 years. The prevalence of astigmatism >2.00 diopters was 30% in Tohono O'odham children during infancy (6 months to O'odham infants show a high prevalence of astigmatism, which decreases in the second year of life. However, the prevalence of high astigmatism in Tohono O'odham children increases by age 2 to <3 years to a level near that seen in infancy and remains at that level until at least age 8 years. Longitudinal data are needed to determine whether the increase in high astigmatism after infancy occurs in infants who had astigmatism as infants or is due to the development of high astigmatism in children who did not show astigmatism during infancy.

The aims of the study were to determine the prevalence of ADHD in a population of high school students and to explore the factors associated with this disorder. This was a cross-sectional study that had included 447 high school students. The diagnosis of ADHD was made by the Adult ADHD Self-Report Scale translated in Arabic language. The sociodemographic and clinical characteristics were evaluated by a preestablished questionnaire. The self-esteem was assessed by the Rosenberg Self-Esteem Scale. The prevalence of ADHD was 18.1%. The logistic regression analysis showed an association between the diagnosis of ADHD and the bad relationships with parents (odds ratio [OR] = 16.43; p antecedents (OR = 12.16; p antecedents (OR = 3.16; p = .009). The prevalence of ADHD in this study was one of the highest prevalence reported. The factors associated with ADHD may have diagnostic and therapeutic implications.

Mahadev D Bhise

Full Text Available In the last few decades, the prevalence of hypertension has been drastically increased in India. The present study estimates the current prevalence of hypertension and its correlates in the state of Maharashtra. The variation in the prevalence of hypertension associated with individual-level characteristics is explained at the community and district level.Data is used from the recent round of District Level Household & Facility Survey (DLHS-4, 2012-13. The DLHS-4 has used the nationally representative sample, collected through multistage stratified sampling procedure. A similar sampling frame, used in NSSO-2007-08, has been followed. The chi-square test is used to show the significance level of the association between the estimated prevalence of hypertension and its correlates. Multilevel regression analysis is carried out to investigate the effects of individual and community level factors on the prevalence of hypertension.The overall prevalence of hypertension is 25% in Maharashtra, and a huge variation in the prevalence of hypertension is found across the districts. Dhule, Gadchiroli (with a low HDI rank, Mumbai and Satara (with higher HDI rank are the districts with the higher (above 30% prevalence of high blood pressure. The prevalence also significantly varies according to different correlates. The prevalence of high blood pressure is higher among elderly population (40%, among males (28%, in the urban areas (27% and in the richest wealth quintile (28%. The prevalence is also higher among cigarette smokers (31%, alcohol consumers (30% and people with obesity (38% as compared to their counterparts. The results of the multilevel analysis show that the older and obese persons are at four-time higher risk of hypertension. Again, age, sex, marital status, place of residence, wealth status, unhealthy habits (i.e. smoking and alcohol consumption and BMI are significantly associated with hypertension. The results of VPC statistics show that 14% of

Burnout is a syndrome of emotional exhaustion, depersonalization, and reduced personal accomplishment. Its prevalence among US physicians exceeds 50% and is higher among residents/fellows. This is important to the practice of neurosurgery, as burnout is associated with adverse physical health, increased risk of substance abuse, and increased medical errors. To date, no study has specifically addressed the prevalence of burnout among neurosurgery residents. To determine and compare the prevalence of burnout among US neurosurgery residents with published rates for residents/fellows and practicing physicians from other specialties. We surveyed 106 US neurosurgery residency training programs to perform a descriptive analysis of the prevalence of burnout among residents. Data on burnout among control groups were used to perform a cross-sectional analysis. Nonparametric tests assessed differences in burnout scores among neurosurgery residents, and the 2-tailed Fisher's exact test assessed burnout between neurosurgery residents and control populations. Of approximately 1200 US neurosurgery residents, 255 (21.3%) responded. The prevalence of burnout was 36.5% (95% confidence interval: 30.6%-42.7%). There was no significant difference in median burnout scores between gender (P = .836), age (P = .183), or postgraduate year (P = .963) among neurosurgery residents. Neurosurgery residents had a significantly lower prevalence of burnout (36.5%) than other residents/fellows (60.0%; P burnout than other residents/fellows and practicing physicians. The underlying causes for these findings were not assessed and are likely multifactorial. Future studies should address possible causes of these findings.

Gastroesophageal reflux disease (GERD) is a common chronic gastrointestinal tract disease. The incidence is higher in Asian and Arab countries. In Saudi Arabia, there are few studies that have assessed the prevalence of GERD among some cities' communities. Hence, this study aims to study the prevalence of GERD among the general population of Saudi Arabia. A cross-sectional study was designed to determine the prevalence of GERD among the community of Saudi Arabia. The sample was randomly gathered through self-administered validated GERD questionnaire (GerdQ) to diagnose GERD, during the period from November to December 2016. The sociodemographic data was assessed for all participants. The data were analysed using Statistical Package for Social Sciences version 21.0 (SPSS); the t -test was used to assess the association of GERD and sociodemographic data. The sample was comprised of 2,043 participants. Female and male were 51.8% and 48.2%, respectively. Mean age was 29.6 years with the standard deviation of 10.5 years. The GERD prevalence was 28.7%. It was found statistically significant among divorced/widow (34.9%, P = 0.003). In contrast, there was no association between GERD's prevalence and gender, age, residence status, education level, occupation, and blood group (P > 0.05). The prevalence of GERD among Saudi population is higher than that in Western countries and East Asia. It affects divorced/widow, obese and those with a sedentary lifestyle. It is advocated that national programs and educational campaigns for prevention of this disease and its complications should be established.

There is uncertainty about the prevalence of food allergy in communities. To assess the prevalence of food allergy by performing a meta-analysis according to the method of assessment used. The foods assessed were cow's milk, hen's egg, peanut, fish, shellfish, and an overall estimate of food allergy. We summarized the information in 5 categories: self-reported symptoms, specific IgE positive, specific skin prick test positive, symptoms combined with sensitization, and food challenge studies. We systematically searched MEDLINE and EMBASE for publications since 1990. The meta-analysis included only original studies. They were stratified by age groups: infant/preschool, school children, and adults. A total of 934 articles were identified, but only 51 were considered appropriate for inclusion. The prevalence of self-reported food allergy was very high compared with objective measures. There was marked heterogeneity between studies regardless of type of assessment or food item considered, and in most analyses this persisted after age stratification. Self-reported prevalence of food allergy varied from 1.2% to 17% for milk, 0.2% to 7% for egg, 0% to 2% for peanuts and fish, 0% to 10% for shellfish, and 3% to 35% for any food. There is a marked heterogeneity in the prevalence of food allergy that could be a result of differences in study design or methodology, or differences between populations. We recommend that measurements be made by using standardized methods, if possible food challenge. We need to be cautious in estimates of prevalence based only on self-reported food allergy.

Full Text Available Research Question: What is the sickness prevalence in the slums of a metropolitan city? Objectives: To estimate the morbidity prevalence with reference to a socio-economic and demographic perspective of the slum population of Delhi. Study Design: A cross-sectional study was conducted and data were collected by a two-stage random sampling method. In the first stage, slum locations were selected and in the second stage households were selected. Participants: Data were collected from 1049 households consisting of 5358 individuals′ information. Results: The overall morbidity prevalence is 15.4%. It is 14.7 and 16.3% for males and females, respectively but the differences are not statistically significant. The reported higher morbidity prevalence and the illiteracy status are significantly associated. Diseases of the respiratory system appear to be very high among slum dwellers. Conclusion: From this study, it can be concluded that the number of years of staying in the slum area, presence of a separate kitchen, type of house, it being Pucca or Kuccha, types of toilet pits or open defecation are the important environmental factors for the reports of higher morbidity patterns from the slum area.

Leptospirosis is a widespread emerging bacterial zoonosis. As the transmission is believed to be predominantly waterborne, human incidence is expected to increase in conjunction with global climate change and associated extreme weather events. Providing more accurate predictions of human leptospirosis requires more detailed information on animal reservoirs that are the source of human infection. We evaluated the prevalence of Leptospira in vertebrates worldwide and its association with taxonomy, geographic region, host biology, ambient temperature, and precipitation patterns. A multivariate regression analysis with a meta-analysis-like approach was used to analyze compiled data extracted from 300 Leptospira-related peer reviewed papers. A fairly uniform Leptospira infection prevalence of about 15% was found in the majority of mammalian families. Higher prevalence was frequently associated with species occupying urban habitats, and this may explain why climatic factors were not significantly correlated with prevalence as consistently as expected. Across different approaches of the multiple regression analyses, the variables most frequently correlated with Leptospira infection prevalence were the host's ability to swim, minimum ambient temperature, and methodologic quality of the study. Prevalence in carnivores was not associated with any climatic variable, and the importance of environmental risk factors were indicated to be of lesser consequence in nonhuman mammals. The dataset is made available for further analysis.

The reported prevalence of myasthenia gravis ranges between 5 and 24 cases per 100,000, and people over 65years account for less than 50% of all cases. The prevalence and clinical characteristics of myasthenia gravis in the county of Osona were studied in patients younger and older than 65. The study draws from the county-based prospective myasthenia gravis register implemented by the Neurology Department at Hospital General de Vic in 1991. The prevalence of myasthenia gravis was 32.89×10 5 inhabitants (95%CI, 23.86-41.91). The standardized prevalence (European population) was 35.47×10 5 inhabitants (95%CI, 26.10-44.84). The ratio of women to men was 1.3. Overall, the group of patients older than 65 accounted for 62.75% of all cases. The prevalence of myasthenia gravis increased considerably in older age groups. No cases were registered among patients under 25years old, prevalence was 21.87×10 5 in the 25 to 64 age group, and prevalence in patients over 65 years increased to 122.35×10 5 . The clinical characteristics prior to treatment and at the cut-off date are similar (P>.05) in patients younger than 65 and those aged 65 and older. These figures show the highest prevalence rate reported to date. This high prevalence is due to the rate observed among patients older than 65. These results provide a new warning that myasthenia gravis may be underdiagnosed in the elderly population. Copyright © 2014 Sociedad Española de Neurología. Publicado por Elsevier España, S.L.U.

A prevalence survey is a time-saving and useful tool for obtaining an overview of healthcare-associated infection (HCAI) either in a single hospital or nationally. Direct comparison of prevalence rates is difficult. We evaluated the impact of case-mix adjustment on hospital-specific prevalences. All five tertiary care, all 15 secondary care and 10 (25% of 40) other acute care hospitals took part in the first national prevalence survey in Finland in 2005. US Centers for Disease Control and Prevention criteria served to define HCAI. The information collected included demographic characteristics, severity of the underlying disease, use of catheters and a respirator, and previous surgery. Patients with HCAI related to another hospital were excluded. Case-mix-adjusted HCAI prevalences were calculated by using a multivariate logistic regression model for HCAI risk and an indirect standardisation method. Altogether, 587 (7.2%) of 8118 adult patients had at least one infection; hospital-specific prevalences ranged between 1.9% and 12.6%. Risk factors for HCAI that were previously known or identified by univariate analysis (age, male gender, intensive care, high Charlson comorbidity and McCabe indices, respirator, central venous or urinary catheters, and surgery during stay) were included in the multivariate analysis for standardisation. Case-mix-adjusted prevalences varied between 2.6% and 17.0%, and ranked the hospitals differently from the observed rates. In 11 (38%) hospitals, the observed prevalence rank was lower than predicted by the case-mix-adjusted figure. Case-mix should be taken into consideration in the interhospital comparison of prevalence rates. Copyright 2010 The Hospital Infection Society. Published by Elsevier Ltd. All rights reserved.

To determine whether the high prevalence of reported asthma in Melbourne schoolchildren is seen in rural Victoria. A questionnaire on respiratory symptoms was distributed to children to be completed by parents and returned to the school. Results were compared with a previous Melbourne study. Two hundred and twenty-seven government and non-government primary schools in five rural regions of Victoria: coast, wheatbelt, riverland, highland and Latrobe valley. All children enrolled in grade 2 were invited to join the study. Parents completed questionnaires for 4661 children after 4886 questionnaires were distributed (response rate, 95%). History of wheeze in the past 12 months. The overall prevalence of wheeze in the last 12 months was 23.6%. There was a significant difference overall in this rate across the five rural areas and Melbourne, with the Latrobe Valley (26.2%) and highland areas (25.0%) having the highest rate, and the wheatbelt the lowest (19.6%). The spectrum of severity of asthma was similarly distributed across rural regions, although severe episodes were significantly more frequently reported by parents from rural areas than by parents in Melbourne. The reported use of bronchodilators and diagnosis of asthma showed a similar pattern of variation to that of the 12-month prevalence of wheeze. The prevalence of asthma in 7-year-old children is similar for rural Victoria as a whole compared with Melbourne, but there is variability in asthma prevalence in individual rural areas which is difficult to account for in terms of known environmental precipitants.

Dietary habits in the Mexican population have changed dramatically over the last few years, which are reflected in increased overweight and obesity prevalence. The aim was to examine the prevalence of metabolic syndrome (MetS) and associated risk factors in Northern Mexican adults aged ≥ 16 years. The study was a population-based cross-sectional nutritional survey carried out in the State of Nuevo León, Mexico. The study included a sub-sample of 1,200 subjects aged 16 and over who took part in the State Survey of Nutrition and Health-Nuevo León 2011/2012. Anthropometric measurements, physical activity, blood pressure and fasting blood tests for biochemical analysis were obtained from all subjects. The prevalence of MetS in Mexican adults aged ≥ 16 years was 54.8%, reaching 73.8% in obese subjects. This prevalence was higher in women (60.4%) than in men (48.9%) and increased with age in both genders. Multivariate analyses showed no evident relation between MetS components and the level of physical activity. Obese adults, mainly women, are particularly at risk of developing MetS, with the associated implications for their health. The increasing prevalence of MetS highlights the need for developing strategies for its early detection and prevention.

Botswana has the second-highest human immunodeficiency virus (HIV) infection rate in the world, with one in three adults infected. However, there is significant geographic variation at the district level and HIV prevalence is heterogeneous with the highest prevalence recorded in Selebi-Phikwe and North East. There is a lack of age-and location-adjusted prevalence maps that could be used for targeting HIV educational programs and efficient allocation of resources to higher risk groups. We used a nationally representative household survey to investigate and explain district level inequalities in HIV rates. A Bayesian geoadditive mixed model based on Markov Chain Monte Carlo techniques was applied to map the geographic distribution of HIV prevalence in the 26 districts, accounting simultaneously for individual, household, and area factors using the 2008 Botswana HIV Impact Survey. Overall, HIV prevalence was 17.6%, which was higher among females (20.4%) than males (14.3%). HIV prevalence was higher in cities and towns (20.3%) than in urban villages and rural areas (16.6% and 16.9%, respectively). We also observed an inverse U-shape association between age and prevalence of HIV, which had a different pattern in males and females. HIV prevalence was lowest among those aged 24 years or less and HIV affected over a third of those aged 25-35 years, before reaching a peak among the 36-49-year age group, after which the rate of HIV infection decreased by more than half among those aged 50 years and over. In a multivariate analysis, there was a statistically significant higher likelihood of HIV among females compared with males, and in clerical workers compared with professionals. The district-specific net spatial effects of HIV indicated a significantly higher HIV rate of 66% (posterior odds ratio of 1.66) in the northeast districts (Selebi-Phikwe, Sowa, and Francistown) and a reduced rate of 27% (posterior odds ratio of 0.73) in Kgalagadi North and Kweneng West districts

Prevalence & consequences of anaemia in pregnancy.

Kalaivani, K

Prevalence of anaemia in India is among the highest in the world. Prevalence of anaemia is higher among pregnant women and preschool children. Even among higher income educated segments of population about 50 per cent of children, adolescent girls and pregnant women are anaemic. Inadequate dietary iron, folate intake due to low vegetable consumption, perhaps low B12 intake and poor bioavailability of dietary iron from the fibre, phytate rich Indian diets are the major factors responsible for high prevalence of anaemia. Increased requirement of iron during growth and pregnancy and chronic blood loss contribute to higher prevalence in specific groups. In India, anaemia is directly or indirectly responsible for 40 per cent of maternal deaths. There is 8 to 10-fold increase in MMR when the Hb falls below 5 g/dl. Early detection and effective management of anaemia in pregnancy can contribute substantially to reduction in maternal mortality. Maternal anaemia is associated with poor intrauterine growth and increased risk of preterm births and low birth weight rates. This in turn results in higher perinatal morbidity and mortality, and higher infant mortality rate. A doubling of low birth weight rate and 2 to 3 fold increase in the perinatal mortality rates is seen when the Hb is anaemia contributes to intergenerational cycle of poor growth in the offspring. Early detection and effective management of anaemia in pregnancy can lead to substantial reduction in undernutrition in childhood, adolescence and improvement in adult height.

Full Text Available Abstract Background Estimates of the annual prevalence for Obsessive Compulsive Disorder (OCD were consistent across the international sites range, 1.9% – 2.5%. The nine population surveys, which used Diagnostic Interview Schedule, estimated a six-month prevalence of OCD ranging from 0.7% to 2.1%. This study performed in order to determine the prevalence of OCD in a population-based study among Iranian adults aged 18 and older and to study the association of them with factors such as sex, marital status, education, type of occupation and residential area. Methods A cross-sectional nationwide epidemiological study of the Iranian population aged 18 and older was designed to estimate the prevalence of psychiatric disorders and their association with the above mentioned factors. 25180 individuals were selected and interviewed through a randomized systematic and cluster sampling method from all Iranian households. Schedule for Affective Disorders and Schizophrenia (SADS and Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV criteria were used in diagnosis of OCD. 250 clinical psychologists interviewed the selected subjects face to face at their homes. Results The prevalence of OCD in Iran is 1.8% (0.7% and 2.8% in males and females; respectively. 50.3% of the survey sample were men, 49.9% women, 29.1% single, 67.45% married, 0.4% separated or divorced, 2.5% widow/widower and 4% undetermined. All of the above-mentioned factors were examined in the univariate and multivariate logistic regression models. Although the data did not fit the models well, but in univariate models, sex, the category "single" of marital status, age, the categories "business" and "housewife" and residential areas showed significant effect adjusting for the factors, but the models didn't fit the data properly. Conclusion The study suggests that the prevalence of OCD is not rare in the community of Iran and is within the range of other countries. Similar to prior

Cadmium Exposure is Associated with the Prevalence of Dyslipidemia

2016-11-01

Full Text Available Background: Cadmium is a widespread environmental and occupational pollutant that accumulates in human body with a biological half-life exceeding 10 years. Cadmium exposure has been demonstrated to increase rates of cardiovascular diseases. Whether occupational cadmium exposure is associated with the increase in the prevalence of dyslipidemia and hence contributes to the risk of cardiovascular diseases is still equivocal. To test the hypothesis that exposure to cadmium is related to the prevalence of dyslipidemia, we examined the associations between blood cadmium concentration and the prevalence of dyslipidemia in workers occupationally exposed to cadmium in China. Methods: A cross-sectional survey on demographic data, blood cadmium level and lipid profile in cadmium exposed workers from seven cadmium smelting factories in central and southwestern China was conducted. We measured blood cadmium concentration and lipid components of 1489 cadmium exposed workers. The prevalence of dyslipidemia was compared across blood cadmium quartiles. Associations between the blood cadmium concentrations and the prevalence of dyslipidemia were assessed using confounder adjusted linear and logistic regressions. Results: The blood cadmium concentration was 3.61±0.84µg/L ( mean ±SD. The prevalence of dyslipidemia in this occupational population was 66.3%. Mean blood cadmium concentration of workers with dyslipedemia was significantly higher than that of workers without dyslipidemia (p Conclusion: Elevated blood cadmium concentration is associated with prevalence of dyslipidemia. Cadmium exposure could alter lipid metabolism in humans. It is imperative to control cadmium exposure of occupational population in cadmium related industries and reduce adverse health effects.

Unity from duality

Townsend, P.

1995-01-01

The author suggest that the discovery of ''hidden'' symmetries in the subatomic world will, in due time succeed in uniting the strong and weak nuclear forces and the electromagnetic force (already successfully united in the Standard Model) with the fourth universal force, gravity, to produce a ''unified theory of everything''. Concepts such as groups, in the context of quantum field theory, supersymmetry and superstrings are explained to back this contention. Recent work on the nature of electromagnetic duality, may, it is argued, increase our comprehension to a level where ''theories of everything'' may emerge. (UK)

2014-08-01

The prevalence of ankyloglossia has been estimated at around 4% of live births. Its prevalence at national level is unknown. Multicenter, prospective observational study. Six hospitals in Asturias took part. All newborns were examined on Sundays, Tuesdays and Thursdays for 3 months. Coryllos and Hazelbaker criteria were used to diagnose ankyloglossia. The prevalence in the 667 newborns examined was 12.11% (95% CI: 9.58 to 14.64), of whom 62% were male. One in 4 children with ankyloglossia had a family history. According to Coryllos' classification, type II was the most common (54%). The prevalence of ankyloglossia in Asturias was 2 to t3 times higher than expected. The diagnostic criteria for ankyloglossia needs to be unified, and further studies are required to determine the association with breastfeeding difficulties and other health problems.

To assess human immunodeficiency virus (HIV) diversity and the prevalence of transmitted drug resistance (TDR) in Guatemala. One hundred forty-five antiretroviral treatment-naïve patients referred to the Roosevelt Hospital in Guatemala City were enrolled from October 2010 to March 2011. Plasma HIV pol sequences were obtained and TDR was assessed with the Stanford algorithm and the World Health Organization (WHO) TDR surveillance mutation list. HIV subtype B was highly prevalent in Guatemala (96.6%, 140/145), and a 2.8% (4/145) prevalence of BF1 recombinants and 0.7% (1/145) prevalence of subtype C viruses were found. TDR prevalence for the study period was 8.3% (12/145) with the Stanford database algorithm (score > 15) and the WHO TDR surveillance mutation list. Most TDR cases were associated with non-nucleoside reverse transcriptase inhibitors (NNRTIs) (83.3%, 10/12); a low prevalence of nucleoside reverse transcriptase inhibitors and protease inhibitors was observed in the cohort (Guatemala. TDR prevalence in Guatemala was at the intermediate level. Most TDR cases were associated with NNRTIs. Further and continuous TDR surveillance is necessary to gain more indepth knowledge about TDR spread and trends in Guatemala and to optimize treatment outcomes in the country.

Andrews, P; Steultjens, M; Riskowski, J

2018-01-01

Chronic widespread pain (CWP) is a significant burden in communities. Understanding the impact of population-dependent (e.g., age, gender) and contextual-dependent (e.g. survey method, region, inequality level) factors have on CWP prevalence may provide a foundation for population-based strategies to address CWP. Therefore, the purpose of this study was to estimate the global prevalence of CWP and evaluate the population and contextual factors associated with CWP. A systematic review of CWP prevalence studies (1990-2017) in the general population was undertaken. Meta-analyses were conducted to determine CWP prevalence, and study population data and contextual factors were evaluated using a meta-regression. Thirty-nine manuscripts met the inclusion criteria. Study CWP prevalence ranged from 1.4% to 24.0%, with CWP prevalence in men ranging from 0.8% to 15.3% and 1.7% to 22.1% in women. Estimated overall CWP prevalence was 9.6% (8.0-11.2%). Meta-regression analyses showed gender, United Nations country development status, and human development index (HDI) influenced CWP prevalence, while survey method, region, methodological and reporting quality, and inequality showed no significant effect on the CWP estimate. Globally CWP affects one in ten individuals within the general population, with women more likely to experience CWP than men. HDI was noted to be the socioeconomic factor related to CWP prevalence, with those in more developed countries having a lower CWP prevalence than those in less developed countries. Most CWP estimates were from developed countries, and CWP estimates from countries with a lower socioeconomic position is needed to further refine the global estimate of CWP. This systematic review and meta-analysis updates the current global CWP prevalence by examining the population-level (e.g. age, gender) and contextual (e.g. country development status; survey style; reporting and methodologic quality) factors associated with CWP prevalence. This analyses

Full Text Available Objectives The primary objective of this study was to determine the prevalence of Anaplasma phagocytophilum infection and exposure in adult feral cats in Massachusetts, an endemic area for A phagocytophilum and its tick vector Ixodes scapularis . The secondary objective was to determine if there were correlations between A phagocytophilum infection and the presence of anemia and thrombocytopenia. Methods Blood samples were collected between June and December 2015 from 175 apparently healthy adult feral cats that were presented to trap and release spay/neuter centers in Massachusetts. Complete blood count, blood smear evaluation, SNAP 4Dx Plus test (IDEXX and A phagocytophilum PCR were performed on all samples to document acute infection (PCR-positive and/or inclusions observed on blood smear and exposure to A phagocytophilum (SNAP 4Dx Plus-positive for A phagocytophilum antibodies. Results The prevalence of exposure to A phagocytophilum in feral cats in Massachusetts was 9.7%, whereas the prevalence of acute infection was 6.9%. All blood smears were negative for Anaplasma species inclusions; therefore, acute infection was defined as testing positive on PCR analysis. No statistically significant correlations were identified for cats that were positive for A phagocytophilum on PCR analysis or SNAP 4Dx Plus test and the presence of anemia or thrombocytopenia. Conclusions and relevance The prevalence of A phagocytophilum exposure in feral cats approaches 10% and is higher than the previously reported national average prevalence of 4.3% in the USA. A phagocytophilum infection may be an emerging infectious disease in cats. Further research is needed to determine the prevalence of clinical illness associated with A phagocytophilum infection in cats living in endemic areas.

Knowledge of a country's cervical cancer (CC) burden is critical to informing decisions about resource allocation to combat the disease; however, many countries lack cancer registries to provide such data. We developed a prognostic model to estimate CC incidence rates in countries without cancer registries, leveraging information on human papilloma virus (HPV) prevalence, screening, and other country-level factors. We used multivariate linear regression models to identify predictors of CC incidence in 40 countries. We extracted age-specific HPV prevalence (10-year age groups) by country from a meta-analysis in women with normal cytology (N = 40) and matched to most recent CC incidence rates from Cancer Incidence in Five Continents when available (N = 36), or Globocan 2008 (N = 4). We evaluated country-level behavioral, economic, and public health indicators. CC incidence was significantly associated with age-specific HPV prevalence in women aged 35-64 (adjusted R-squared 0.41) ("base model"). Adding geographic region to the base model increased the adjusted R-squared to 0.77, but the further addition of screening was not statistically significant. Similarly, country-level macro-indicators did not improve predictive validity. Age-specific HPV prevalence at older ages was found to be a better predictor of CC incidence than prevalence in women under 35. However, HPV prevalence could not explain the entire CC burden as many factors modify women's risk of progression to cancer. Geographic region seemed to serve as a proxy for these country-level indicators. Our analysis supports the assertion that conducting a population-based HPV survey targeting women over age 35 can be valuable in approximating the CC risk in a given country. Copyright © 2012 UICC.

Obesity is associated with adverse health outcomes in people with and without disabilities. However, little is known about disability prevalence among people who are obese. The purpose of this study is to determine the prevalence and type of disability among adults who are obese. Pooled data from the 2003-2009 National Health Interview Survey (NHIS) were analyzed to obtain national prevalence estimates of disability, disability type and obesity. The disability prevalence was stratified by body mass index (BMI): healthy weight (BMI 18.5-reported a disability. In contrast, 26.7% of those with a healthy weight and 28.5% of those who were overweight reported a disability. The most common disabilities among respondents with obesity were movement difficulty (32.5%) and work limitation (16.6%). This research contributes to the literature on obesity by including disability as a demographic in assessing the burden of obesity. Because of the high prevalence of disability among those who are obese, public health programs should consider the needs of those with disabilities when designing obesity prevention and treatment programs.

Full Text Available Background. This paper investigates two issues: do ethnic/racial groups with high HIV prevalences also have higher prevalences of other STIs? and is HIV prevalence by ethnic group correlated with the prevalence of circumcision, concurrency, or having more than one partner in the preceding year? Methods. We used Spearman’s correlation to estimate the association between the prevalence of HIV per ethnic/racial group and HSV-2, syphilis, symptoms of an STI, having more than one partner in the past year, concurrency, and circumcision in Kenya, South Africa, the United Kingdom, and the United States. Results. We found that in each country HSV-2, syphilis, and symptomatic STIs were positively correlated with HIV prevalence (HSV-2: Kenya rho = 0.50, P = 0.207; South Africa rho-1, P = 0.000; USA rho-1, P = 0.000, Syphilis: Kenya rho = 0.33, P = 0.420; South Africa rho-1, P = 0.000; USA rho-1, P = 0.000, and STI symptoms: Kenya rho = 0.92, P = 0.001; South Africa rho-1, P = 0.000; UK rho = 0.87, P = 0.058; USA rho-1, P = 0.000. The prevalence of circumcision was only negatively associated with HIV prevalence in Kenya. Both having more than one partner in the previous year and concurrency were positively associated with HIV prevalence in all countries (concurrency: Kenya rho = 0.79, P = 0.036; South Africa rho-1, P = 0.000; UK 0.87, P = 0.058; USA rho-1, P = 0.000 and multiple partners: Kenya rho = 0.82, P = 0.023; South Africa rho-1, P = 0.000; UK rho = 0.87, P = 0.058; USA rho-1, P = 0.000. Not all associations were statistically significant. Conclusion. Further attention needs to be directed to what determines higher rates of partner change and concurrency in communities with high STI prevalence.

The present analyses were conducted to: (1 estimate the country-specific prevalence of inadequate zinc intake; and (2 investigate relationships between country-specific estimated prevalence of dietary zinc inadequacy and dietary patterns and stunting prevalence. METHODOLOGY AND PRINCIPAL FINDINGS: National food balance sheet data were obtained from the Food and Agriculture Organization of the United Nations. Country-specific estimated prevalence of inadequate zinc intake were calculated based on the estimated absorbable zinc content of the national food supply, International Zinc Nutrition Consultative Group estimated physiological requirements for absorbed zinc, and demographic data obtained from United Nations estimates. Stunting data were obtained from a recent systematic analysis based on World Health Organization growth standards. An estimated 17.3% of the world's population is at risk of inadequate zinc intake. Country-specific estimated prevalence of inadequate zinc intake was negatively correlated with the total energy and zinc contents of the national food supply and the percent of zinc obtained from animal source foods, and positively correlated with the phytate: zinc molar ratio of the food supply. The estimated prevalence of inadequate zinc intake was correlated with the prevalence of stunting (low height-for-age in children under five years of age (r = 0.48, P<0.001. CONCLUSIONS AND SIGNIFICANCE: These results, which indicate that inadequate dietary zinc intake may be fairly common, particularly in Sub-Saharan Africa and South Asia, allow inter-country comparisons regarding the relative likelihood of zinc deficiency as a public health problem. Data from these analyses should be used to determine

The study aimed to assess the prevalence and causes of corneal blindness in a rural northern Chinese population. Cross-sectional study. The cluster random sampling method was used to select the sample. This population-based study included 11 787 participants of all ages in rural Heilongjiang Province, China. These participants underwent a detailed interview and eye examination that included the measurement of visual acuity, slit-lamp biomicroscopy and direct ophthalmoscopy. An eye was considered to have corneal blindness if the visual acuity was blindness and low vision. Among the 10 384 people enrolled in the study, the prevalence of corneal blindness is 0.3% (95% confidence interval 0.2-0.4%). The leading cause was keratitis in childhood (40.0%), followed by ocular trauma (33.3%) and keratitis in adulthood (20.0%). Age and illiteracy were found to be associated with an increased prevalence of corneal blindness. Blindness because of corneal diseases in rural areas of Northern China is a significant public health problem that needs to be given more attention. © 2013 Royal Australian and New Zealand College of Ophthalmologists.

2017-05-01

Congenital amusia (commonly known as tone deafness) is a lifelong musical disorder that affects 4% of the population according to a single estimate based on a single test from 1980. Here we present the first large-based measure of prevalence with a sample of 20 000 participants, which does not rely on self-referral. On the basis of three objective tests and a questionnaire, we show that (a) the prevalence of congenital amusia is only 1.5%, with slightly more females than males, unlike other developmental disorders where males often predominate; (b) self-disclosure is a reliable index of congenital amusia, which suggests that congenital amusia is hereditary, with 46% first-degree relatives similarly affected; (c) the deficit is not attenuated by musical training and (d) it emerges in relative isolation from other cognitive disorder, except for spatial orientation problems. Hence, we suggest that congenital amusia is likely to result from genetic variations that affect musical abilities specifically.

To estimate the prevalence of systemic sclerosis (SSc) using population-based administrative data, and to assess the sensitivity of case ascertainment approaches. We ascertained SSc cases from Quebec physician billing and hospitalization databases (covering approximately 7.5 million individuals). Three case definition algorithms were compared, and statistical methods accounting for imperfect case ascertainment were used to estimate SSc prevalence and case ascertainment sensitivity. A hierarchical Bayesian latent class regression model that accounted for possible between-test dependence conditional on disease status estimated the effect of patient characteristics on SSc prevalence and the sensitivity of the 3 ascertainment algorithms. Accounting for error inherent in both the billing and the hospitalization data, we estimated SSc prevalence in 2003 at 74.4 cases per 100,000 women (95% credible interval [95% CrI] 69.3-79.7) and 13.3 cases per 100,000 men (95% CrI 11.1-16.1). Prevalence was higher for older individuals, particularly in urban women (161.2 cases per 100,000, 95% CrI 148.6-175.0). Prevalence was lowest in young men (in rural areas, as low as 2.8 cases per 100,000, 95% CrI 1.4-4.8). In general, no single algorithm was very sensitive, with point estimates for sensitivity ranging from 20-73%. We found marked differences in SSc prevalence according to age, sex, and region. In general, no single case ascertainment approach was very sensitive for SSc. Therefore, using data from multiple sources, with adjustment for the imperfect nature of each, is an important strategy in population-based studies of SSc and similar conditions.

Teen drivers' over-involvement in crashes has been attributed to a variety of factors, including distracted driving. With the rapid development of in-vehicle systems and portable electronic devices, the burden associated with distracted driving is expected to increase. The current study identifies predictors of secondary task engagement among teenage drivers and provides basis for interventions to reduce distracted driving behavior. We described the prevalence of secondary tasks by type and driving conditions and evaluated the associations between the prevalence of secondary task engagement, driving conditions, and selected psychosocial factors. The private vehicles of 83 newly-licensed teenage drivers were equipped with Data Acquisition Systems (DAS), which documented driving performance measures, including secondary task engagement and driving environment characteristics. Surveys administered at licensure provided psychosocial measures. Overall, teens engaged in a potentially distracting secondary task in 58% of sampled road clips. The most prevalent types of secondary tasks were interaction with a passenger, talking/singing (no passenger), external distraction, and texting/dialing the cell phone. Secondary task engagement was more prevalent among those with primary vehicle access and when driving alone. Social norms, friends' risky driving behaviors, and parental limitations were significantly associated with secondary task prevalence. In contrast, environmental attributes, including lighting and road surface conditions, were not associated with teens' engagement in secondary tasks. Our findings indicated that teens engaged in secondary tasks frequently and poorly regulate their driving behavior relative to environmental conditions. Practical applications: Peer and parent influences on secondary task engagement provide valuable objectives for countermeasures to reduce distracted driving among teenage drivers.

2017-10-01

Full Text Available Published data on the prevalence of autism spectrum disorders point to a significant increase in this indicator. This increase is being studied in numerous publications of analysis, meta-analysis and systematic reviews. The prevalence indicates the proportion of people who suffer at a given time or are diagnosed with a disease. The consequences of the increasing prevalence are relevant from the point of health, social and educational, but especially relevant when as is the case, the cause of the disorder is unknown. It is in this sense that the prevalence study gains importance in order to delimit various circumstances that may give clues to the possible cause or causes that generate disorder. This article reviews studies, summarizes the last data, and reflects on them and possible causes that justify the increased reporting. It looks like these epidemiological indicators can or are influenced by possible methodological flaws behind, which can explain the variations between studies and others. It concludes by stating the need population studies and monitoring that allows us to know the reality of the evolution of these disorders in order to provide reliable information to those responsible for the institutions involved in the detection and treatment of ASD.

Background and Aims Dietary habits in the Mexican population have changed dramatically over the last few years, which are reflected in increased overweight and obesity prevalence. The aim was to examine the prevalence of metabolic syndrome (MetS) and associated risk factors in Northern Mexican adults aged ≥16 years. Methods and Results The study was a population-based cross-sectional nutritional survey carried out in the State of Nuevo León, Mexico. The study included a sub-sample of 1,200 subjects aged 16 and over who took part in the State Survey of Nutrition and Health–Nuevo León 2011/2012. Anthropometric measurements, physical activity, blood pressure and fasting blood tests for biochemical analysis were obtained from all subjects. The prevalence of MetS in Mexican adults aged ≥16 years was 54.8%, reaching 73.8% in obese subjects. This prevalence was higher in women (60.4%) than in men (48.9%) and increased with age in both genders. Multivariate analyses showed no evident relation between MetS components and the level of physical activity. Conclusions Obese adults, mainly women, are particularly at risk of developing MetS, with the associated implications for their health. The increasing prevalence of MetS highlights the need for developing strategies for its early detection and prevention. PMID:25141255

Full Text Available Background. This study assesses the lifetime and active prevalence of epilepsy in Spain in people older than 18 years. Methods. EPIBERIA is a population-based epidemiological study of epilepsy prevalence using data from three representative Spanish regions (health districts in Zaragoza, Almería, and Seville between 2012 and 2013. The study consisted of two phases: screening and confirmation. Participants completed a previously validated questionnaire (EPIBERIA questionnaire over the telephone. Results. A total of 1741 valid questionnaires were obtained, including 261 (14.99% raising a suspicion of epilepsy. Of these suspected cases, 216 (82.75% agreed to participate in phase 2. Of the phase 2 participants, 22 met the International League Against Epilepsy’s diagnostic criteria for epilepsy. The estimated lifetime prevalence, adjusted by age and sex per 1,000 people, was 14.87 (95% CI: 9.8–21.9. Active prevalence was 5.79 (95% CI: 2.8–10.6. No significant age, sex, or regional differences in prevalence were detected. Conclusions. EPIBERIA provides the most accurate estimate of epilepsy prevalence in the Mediterranean region based on its original methodology and its adherence to ILAE recommendations. We highlight that the lifetime prevalence and inactive epilepsy prevalence figures observed here were compared to other epidemiological studies.

To estimate the prevalence of smoking in workers from hospitals within the Catalan Network for Smoke-free hospitals from 2009 to 2012 according to workers' sociodemographic characteristics and the type of hospital. A meta-analysis was performed of prevalence surveys from representative samples of workers from 45 hospitals. The combined prevalence for all hospitals was calculated using a regression model with a random effects model weighted by sample size. The overall prevalence of smoking was 28.1% (95%CI: 26.1 to 30.0%) with a maximum and minimum of 40.3% and 19.1%, respectively. The health professionals with the lowest prevalence of smoking were physicians (16.4%; 95%CI: 12.9 to 19.9) and nurses (25.4%; 95%CI 21.6 to 29.2). The prevalence of smoking in hospital health workers was lower than in the general population of working age. Physicians were the group with the lowest smoking prevalence. Smoking cessation should be promoted among other professional groups. Copyright © 2015 SESPAS. Published by Elsevier Espana. All rights reserved.

BACKGROUND: Excessive alcohol use has been implicated as a risk factor in the development of psoriasis, particularly in men. Despite this, little is known of the incidence or prevalence of psoriasis in patients who misuse alcohol. OBJECTIVE: To assess the prevalence of psoriasis in patients with alcoholic liver disease. METHODS: In total, 100 patients with proven alcoholic liver disease were surveyed for a history of psoriasis and a full skin examination was performed if relevant. RESULTS: Of the 100 patients, 15 reported a history of psoriasis and another 8 had evidence of current activity, suggesting a prevalence (past or present) of 15% in this group of patients. CONCLUSION: It would appear that the prevalence of psoriasis in patients who misuse alcohol is much higher than the 1-3% variously quoted in the general population.

Asthma is a chronic inflammatory airway disease whose prevalence has increased, especially in developed countries; the results of studies of asthma prevalence vary in different populations and even within the same country; in Mexico we observed fluctuations in prevalence of asthma from 7% to 33%. To determine the prevalence of asthma and severity of symptoms as risk indicators in school population in cities in various states of Mexico. A descriptive study of detection of asthma prevalence and analytical-comparative observational study of determination of symptoms of asthma. The surveys were applied to preschool, elementary, middle and high school population, in the cities of Puebla, Puebla; Tulancingo, Hidalgo; Tlaxcala, Tlaxcala, and Cancún, Quintana Roo; new validated questionnaire was used as instrument: Asthma Diagnostic Questionnaire for Epidemiologic Studies, consisting of eight questions with summation value for diagnosis. 8,754 surveys showed a 14% prevalence in Puebla, 17% in Tulancingo, 7% in Tlaxcala, and 14% in Cancún; average in four cities surveyed was 13%; the strength of association with asthma symptoms in descending order with significant odds ratio were: recurrent wheezing, breathlessness, chest tightness, recurrent cough, cough cold, recurrent cold symptoms, predominantly nocturnal cough, cough that increases with exercise. The average prevalence of asthma in the surveyed cities was 13% and the main symptoms indicators of risk of asthma in school children were: recurrent wheezing, breathlessness, chest tightness and recurrent cough.
